| CVE-2026-32136 | AdGuard Home is a network-wide software for blocking ads and tracking. Prior to 0.107.73, an unauthenticated remote attacker can bypass all authentication in AdGuardHome by sending an HTTP/1.1 request that requests an upgrade to HTTP/2 cleartext (h2c). Once the upgrade is accepted, the resulting HTTP/2 connection is handled by the inner mux, which has no authentication middleware attached. All subsequent HTTP/2 requests on that connection are processed as fully authenticated, regardless of wheth | [email protected] | 9.8 | 0.73% | 2026-03-11 | 2026-03-13 |
| CVE-2026-24904 | TrustTunnel is an open-source VPN protocol with a rule bypass issue in versions prior to 0.9.115. In `tls_listener.rs`, `TlsListener::listen()` peeks 1024 bytes and calls `extract_client_random(...)`. If `parse_tls_plaintext` fails (for example, a fragmented/partial ClientHello split across TCP writes), `extract_client_random` returns `None`. In `rules.rs`, `RulesEngine::evaluate` only evaluates `client_random_prefix` when `client_random` is `Some(...)`. As a result, when extraction fails (`clie | [email protected] | 5.3 | 0.26% | 2026-01-29 | 2026-02-20 |
| CVE-2026-24902 | TrustTunnel is an open-source VPN protocol with a server-side request forgery and and private network restriction bypass in versions prior to 0.9.114. In `tcp_forwarder.rs`, SSRF protection for `allow_private_network_connections = false` was only applied in the `TcpDestination::HostName(peer)` path. The `TcpDestination::Address(peer) => peer` path proceeded to `TcpStream::connect()` without equivalent checks (for example `is_global_ip`, `is_loopback`), allowing loopback/private targets to be rea | [email protected] | 7.1 | 0.23% | 2026-01-29 | 2026-02-20 |
| CVE-2025-51497 | An issue was discovered in AdGuard plugin before 1.11.22 for Safari on MacOS. AdGaurd verbosely logged each url that Safari accessed when the plugin was active. These logs went into the MacOS general logs for any unsandboxed process to read. This may be disabled in version 1.11.22. | [email protected] | 5.5 | 0.08% | 2025-07-17 | 2025-10-09 |
| CVE-2023-41173 | AdGuard DNS before 2.2 allows remote attackers to cause a denial of service via malformed UDP packets. | [email protected] | 7.5 | 0.61% | 2023-08-25 | 2026-01-14 |
| CVE-2022-45770 | Improper input validation in adgnetworkwfpdrv.sys in Adguard For Windows x86 through 7.11 allows local privilege escalation. | [email protected] | 7.8 | 0.61% | 2023-01-26 | 2025-03-31 |
| CVE-2022-32175 | In AdGuardHome, versions v0.95 through v0.108.0-b.13 are vulnerable to Cross-Site Request Forgery (CSRF), in the custom filtering rules functionality. An attacker can persuade an authorized user to follow a malicious link, resulting in deleting/modifying the custom filtering rules. | [email protected] | 5.4 | 0.27% | 2022-10-11 | 2025-05-20 |
| CVE-2021-27935 | An issue was discovered in AdGuard before 0.105.2. An attacker able to get the user's cookie is able to bruteforce their password offline, because the hash of the password is stored in the cookie. | [email protected] | 7.5 | 4.12% | 2021-03-03 | 2024-11-21 |
