AdGuard Home Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Security

Incorrect handling of sensitive files permissions on Windows ([#7314]).

Changed

Improved filtering performance (#6818).

Fixed

Repetitive statistics log messages (#7338).
Custom client cache (#7250).
Missing runtime clients with information from the system hosts file on first AdGuard Home start (#7315).

v0.107.53 - 2024-10-03

See also the v0.107.53 GitHub milestone.

Security

Previous versions of AdGuard Home allowed users to add any system file it had access to as filters, exposing them to be world-readable. To prevent this, AdGuard Home now allows adding filtering-rule list files only from files matching the patterns enumerated in the filtering.safe_fs_patterns property in the configuration file.

We thank @itz-d0dgy for reporting this vulnerability, designated CVE-2024-36814, to us.
Additionally, AdGuard Home will now try to change the permissions of its files and directories to more restrictive ones to prevent similar vulnerabilities as well as limit the access to the configuration.

We thank @go-compile for reporting this vulnerability, designated CVE-2024-36586, to us.
Go version has been updated to prevent the possibility of exploiting the Go vulnerabilities fixed in 1.23.2.

Added

Support for 64-bit RISC-V architecture (#5704).
Ecosia search engine is now supported in safe search (#5009).

Changed

Upstream server URL domain names requirements has been relaxed and now follow the same rules as their domain specifications.

Configuration changes

In this release, the schema version has changed from 28 to 29.

The new array filtering.safe_fs_patterns contains glob patterns for paths of files that can be added as local filtering-rule lists. The migration should add list files that have already been added, as well as the default value, $DATA_DIR/userfilters/*.

Fixed

Property clients.runtime_sources.dhcp in the configuration file not taking effect.
Stale Google safe search domains list (#7155).
Bing safe search from Edge sidebar (#7154).
Text overflow on the query log page (#7119).

Known issues

Due to the complexity of the Windows permissions architecture and poor support from the standard Go library, we have to postpone the proper automated Windows fix until the next release.

Temporary workaround: Set the permissions of the AdGuardHome directory to more restrictive ones manually. To do that:
1. Locate the AdGuardHome directory.
2. Right-click on it and navigate to Properties → Security → Advanced.
3. (You might need to disable permission inheritance to make them more restricted.)
4. Adjust to give the Full control access to only the user which runs AdGuard Home. Typically, Administrator.

v0.107.52 - 2024-07-04

See also the v0.107.52 GitHub milestone.

Security

Go version has been updated to prevent the possibility of exploiting the Go vulnerabilities fixed in Go 1.22.5.

Added

The ability to disable logging using the new log.enabled configuration property (#7079).

Changed

Frontend rewritten in TypeScript.
The systemd-based service now uses journal for logging by default. It also doesn't create the /var/log/ directory anymore (#7053).

NOTE: With an installed service for changes to take effect, you need to reinstall the service using -r flag of the install script or via the CLI (with root privileges):
```
./AdGuardHome -s uninstall
./AdGuardHome -s install
```
Don't forget to backup your configuration file and other important data before reinstalling the service.

Deprecated

Node 18 support, Node 20 will be required in future releases.

Fixed

Panic caused by missing user-specific blocked services object in configuration file (#7069).
Tracking /etc/hosts file changes causing panics within particular filesystems on start (#7076).

Deprecated

Currently, AdGuard Home skips persistent clients that have duplicate fields when reading them from the configuration file. This behaviour is deprecated and will cause errors on startup in a future release.

Fixed

Acceptance of duplicate UIDs for persistent clients at startup. See also the section on client settings on the Wiki page.
Domain specifications for top-level domains not considered for requests to unqualified domains (#6744).
Support for link-local subnets, i.e. fe80::/16, as client identifiers (#6312).
Issues with QUIC and HTTP/3 upstreams on older Linux kernel versions (#6422).
YouTube restricted mode is not enforced by HTTPS queries on Firefox.

Currently, AdGuard Home uses a best-effort algorithm to fix invalid IDs of filtering-rule lists on startup. This feature is deprecated, and invalid IDs will cause errors on startup in a future version.
Node.JS 16. Future versions will require at least Node.JS 18 to build.

Fixed

Resetting DNS upstream mode when applying unrelated settings (#6851).
Symbolic links to the configuration file begin replaced by a copy of the real file upon startup on FreeBSD (#6717).

Ability to define custom directories for storage of query log files and statistics (#5992).

Changed

Private rDNS resolution (dns.use_private_ptr_resolvers in YAML configuration) now requires a valid "Private reverse DNS servers", when enabled (#6820).

NOTE: Disabling private rDNS resolution behaves effectively the same as if no private reverse DNS servers provided by user and by the OS.

Fixed

Statistics for 7 days displayed by day on the dashboard graph (#6712).
Missing "served from cache" label on long DNS server strings (#6740).
Incorrect tracking of the system hosts file's changes (#6711).

Security

Go version has been updated to prevent the possibility of exploiting the Go vulnerabilities fixed in Go 1.21.8.

Added

Context menu item in the Query Log to add a Client to the Persistent client list (#6679).

Changed

Starting with this release our scripts are using Go's forward compatibility mechanism for updating the Go version.

Important note for porters: This change means that if your go version is 1.21+ but is different from the one required by AdGuard Home, the go tool will automatically download the required version.

If you want to use the version installed on your builder, run:
```
go get go@$YOUR_VERSION
go mod tidy
```
and call make with GOTOOLCHAIN=local.

Deprecated

Go 1.21 support. Future versions will require at least Go 1.22 to build.

Fixed

The field "upstream_mode" in POST /control/dns_config and GET /control/dns_info HTTP APIs now accepts load_balance value. Check openapi/CHANGELOG.md for more details.

Configuration changes

In this release, the schema version has changed from 27 to 28.

The new property clients.persistent.*.uid, which is a unique identifier of the persistent client.
The properties dns.all_servers and dns.fastest_addr were removed, their values migrated to newly added field dns.upstream_mode that describes the logic through which upstreams will be used. See also a Wiki page.
```
# BEFORE:
'dns':
    # …
    'all_servers': true
    'fastest_addr': true

# AFTER:
'dns':
    # …
    'upstream_mode': 'parallel'

Added

Ability to ignore queries for the root domain, such as NS . queries (#5990).

Changed

Improved CPU and RAM consumption during updates of filtering-rule lists.

Configuration changes

In this release, the schema version has changed from 23 to 24.

Properties starting with log_, and verbose property, which used to set up logging are now moved to the new object log containing new properties file, max_backups, max_size, max_age, compress, local_time, and verbose:

# BEFORE:

Incorrect setting of Parental Control cache size.
Excessive RAM and CPU consumption by Safe Browsing and Parental Control filters (#5896).

Removed

The HEALTHCHECK section and the use of tini in the ENTRYPOINT section in Dockerfile (#5939). They caused a lot of issues, especially with tools like docker-compose and podman.

NOTE: Some Docker tools may cache ENTRYPOINT sections, so some users may be required to backup their configuration, stop the container, purge the old image, and reload it from scratch.

v0.107.33 - 2023-07-03

See also the v0.107.33 GitHub milestone.

Added

The new command-line flag --web-addr is the address to serve the web UI on, in the host:port format.

The ability to edit rewrite rules via PUT /control/rewrite/update HTTP API and the Web UI (#1577).

Changed

Configuration changes

In this release, the schema version has changed from 20 to 23.

# AFTER:
'http':
  'address': '1.2.3.4:8080'
  'session_ttl': '720h'
```
Note that the new http.session_ttl property is now a duration string. To rollback this change, remove the new object http, set back bind_host, bind_port, web_session_ttl, and change the schema_version back to 22.

```
# BEFORE:
'statistics':
  # …
  'interval': 1

# AFTER:
'dns':
  # …
  'edns_client_subnet':
    'enabled': false

  'interval': '2160h'
  'size_memory': 1000
  'ignored': []
```
To rollback this change, rename and move properties back into the dns object, remove querylog object and querylog.ignored property, and change the schema_version back to 14.

Deprecated

v0.107.23 - 2023-02-01

See also the v0.107.23 GitHub milestone.

Added

DNS64 support (#5117). The function may be enabled with new use_dns64 property under dns object in the configuration along with dns64_prefixes, the set of exclusion prefixes to filter AAAA responses. The Well-Known Prefix (64:ff9b::/96) is used if no custom prefixes are specified.

Fixed

Filtering rules with * as the hostname not working properly (#5245).
Various dark theme bugs (#5375).

Removed

The “beta frontend” and the corresponding APIs. They never quite worked properly, and the future new version of AdGuard Home API will probably be different.

Added

The warning message when adding a certificate having no IP addresses (#4898).
Several new blockable services (#3972). Those will now be more in sync with the services that are already blockable in AdGuard DNS.
A new HTTP API, GET /control/blocked_services/all, that lists all available blocked services and their data, such as SVG icons (#3972).
The new optional tls.override_tls_ciphers property, which allows overriding TLS ciphers used by AdGuard Home (#4925, #4990).
The ability to serve DNS on link-local IPv6 addresses (#2926).
The ability to put ClientIDs into DNS-over-HTTPS hostnames as opposed to URL paths (#3418). Note that AdGuard Home checks the server name only if the URL does not contain a ClientID.

Responses for which the DNSSEC validation had explicitly been omitted aren't cached now (#4942).
Web UI not switching to HTTP/3 (#4986, #4993).

v0.107.16 - 2022-10-07

This is a security update. There is no GitHub milestone, since no GitHub issues were resolved.

Security

Go version has been updated to prevent the possibility of exploiting the CVE-2022-2879, CVE-2022-2880, and CVE-2022-41715 Go vulnerabilities fixed in Go 1.18.7.

v0.107.15 - 2022-10-03

See also the v0.107.15 GitHub milestone.

Security

As an additional CSRF protection measure, AdGuard Home now ensures that requests that change its state but have no body (such as POST /control/stats_reset requests) do not have a Content-Type header set on them (#4970).

Added

Experimental HTTP/3 Support

See #3955 and the related issues for more details. These features are still experimental and may break or change in the future.

DNS-over-HTTP/3 DNS and web UI client request support. This feature must be explicitly enabled by setting the new property dns.serve_http3 in the configuration file to true.
DNS-over-HTTP upstreams can now upgrade to HTTP/3 if the new configuration file property dns.use_http3_upstreams is set to true.
Upstreams with forced DNS-over-HTTP/3 and no fallback to prior HTTP versions using the h3:// scheme.

Fixed

User-specific blocked services not applying correctly (#4945, #4982, #4983).
only application/json is allowed errors in various APIs (#4970).

v0.107.14 - 2022-09-29

See also the v0.107.14 GitHub milestone.

Security

A Cross-Site Request Forgery (CSRF) vulnerability has been discovered. We thank Daniel Elkabes from Mend.io for reporting this vulnerability to us. This is CVE-2022-32175.

`SameSite` Policy

The SameSite policy on the AdGuard Home session cookies is now set to Lax. Which means that the only cross-site HTTP request for which the browser is allowed to send the session cookie is navigating to the AdGuard Home domain.

Users are strongly advised to log out, clear browser cache, and log in again after updating.

Removal Of Plain-Text APIs (BREAKING API CHANGE)

We have implemented several measures to prevent such vulnerabilities in the future, but some of these measures break backwards compatibility for the sake of better protection.

The following APIs, which previously accepted or returned text/plain data, now accept or return data as JSON. All new formats for the request and response bodies are documented in openapi/openapi.yaml and openapi/CHANGELOG.md.

GET /control/i18n/current_language;
POST /control/dhcp/find_active_dhcp;
POST /control/filtering/set_rules;
POST /control/i18n/change_language.

Stricter Content-Type Checks (BREAKING API CHANGE)

All JSON APIs that expect a body now check if the request actually has Content-Type set to application/json.

Other Security Changes

Weaker cipher suites that use the CBC (cipher block chaining) mode of operation have been disabled (#2993).

Added

Support for plain (unencrypted) HTTP/2 (#4930). This is useful for AdGuard Home installations behind a reverse proxy.

Fixed

Incorrect path template in DDR responses (#4927).

v0.107.13 - 2022-09-14

See also the v0.107.13 GitHub milestone.

Added

The new optional dns.ipset_file property, which can be set in the configuration file. It allows loading the ipset list from a file, just like dns.upstream_dns_file does for upstream servers (#4686).

Changed

The minimum DHCP message size is reassigned back to BOOTP's constraint of 300 bytes (#4904).

Fixed

Panic when adding a static lease within the disabled DHCP server (#4722).

NOTE: This modifier affects all the parameters in the response and not only the requested ones.
A new HTTP API, GET /control/blocked_services/services, that lists all available blocked services (#4535).

Changed

The DHCP options handling is now closer to the RFC 2131 (#4705).

Updater no longer expects a hardcoded name for AdGuardHome executable (#4219).
Inconsistent names of runtime clients from hosts files (#4683).
PTR requests for addresses leased by DHCP will now be resolved into hostnames under dhcp.local_domain_name (#4699).
Broken service installation on OpenWrt (#4677).

v0.107.7 - 2022-06-06

Security

Go version has been updated to prevent the possibility of exploiting the CVE-2022-29526, CVE-2022-30634, CVE-2022-30629, CVE-2022-30580, and CVE-2022-29804 Go vulnerabilities.
Enforced password strength policy (#3503).

Added

Support for the final DNS-over-QUIC standard, RFC 9250 (#4592).
Support upstreams for subdomains of a domain only (#4503).
The ability to control each source of runtime clients separately via clients.runtime_sources configuration object (#3020).
The ability to customize the set of networks that are considered private through the new dns.private_networks property in the configuration file (#3142).

Logs are now collected by default on FreeBSD and OpenBSD when AdGuard Home is installed as a service (#4213).

Changed

On OpenBSD, the daemon script now uses the recommended /bin/ksh shell instead of the /bin/sh one (#4533). To apply this change, backup your data and run AdGuardHome -s uninstall && AdGuardHome -s install.
The default DNS-over-QUIC port number is now 853 instead of 754 in accordance with RFC 9250 (#4276).
Reverse DNS now has a greater priority as the source of runtime clients' information than ARP neighborhood.
Improved detection of runtime clients through more resilient ARP processing (#3597).
The TTL of responses served from the optimistic cache is now lowered to 10 seconds.
Domain-specific private reverse DNS upstream servers are now validated to allow only *.in-addr.arpa and *.ip6.arpa domains pointing to locally-served networks (#3381).

NOTE: If you already have invalid entries in your configuration, consider removing them manually, since they essentially had no effect.
Response filtering is now performed using the record types of the answer section of messages as opposed to the type of the question (#4238).
Instead of adding the build time information, the build scripts now use the standardized environment variable SOURCE_DATE_EPOCH to add the date of the commit from which the binary was built (#4221). This should simplify reproducible builds for package maintainers and those who compile their own AdGuard Home.
The property local_domain_name is now in the dhcp object in the configuration file to avoid confusion (#3367).
The dns.bogus_nxdomain property in the configuration file now supports CIDR notation alongside IP addresses (#1730).

Configuration changes

In this release, the schema version has changed from 12 to 14.

Object clients, which in schema versions 13 and earlier was an array of actual persistent clients, is now consist of persistent and runtime_sources properties:
```
# BEFORE:
'clients':
- name: client-name
  # …

# AFTER:
'clients':
  'persistent':
    - name: client-name
      # …
  'runtime_sources':
    whois: true
    arp: true
    rdns: true
    dhcp: true
    hosts: true
```
The value for clients.runtime_sources.rdns property is taken from dns.resolve_clients property. To rollback this change, remove the runtime_sources property, move the contents of persistent into the clients itself, the value of clients.runtime_sources.rdns into the dns.resolve_clients, and change the schema_version back to 13.
Property local_domain_name, which in schema versions 12 and earlier used to be a part of the dns object, is now a part of the dhcp object:
```
# BEFORE:
'dns':
  # …
  'local_domain_name': 'lan'

# AFTER:
'dhcp':
  # …
