CVE-2025-65114

Apache Traffic Server before 6.2.1 generates a coredump when there is a mismatch between content length and chunked encoding.

Apache Traffic Server versions 6.0.0 to 6.2.0 are affected by an HPACK Bomb Attack.

Unspecified vulnerability in Apache Traffic Server versions 3.x through 3.2.5, 4.x before 4.2.1.1, and 5.x before 5.0.1. This vulnerability may be related to health checks, but its impact and attack vectors are unknown.

Apache Traffic Server can resume a TLS session across SNI virtual hosts without re-verifying a client certificate required by the resumed host's verify_client STRICT policy. This affects versions 8.0.0 through 8.1.11, 9.0.0 through 9.2.15, 10.0.0 through 10.1.4, and 10.2.0.

Apache Traffic Server's default outbound session-sharing policy can reuse a pooled TLS session authenticated with one client certificate for a transaction configured to present a different one. This affects versions 9.0.0 through 9.2.15, 10.0.0 through 10.1.4, and 10.2.0.

Apache Traffic Server's origin_server_auth plugin lets a client force signing of attacker-chosen AWS request headers under the proxy's own credentials. Affects versions 8.0.0–8.1.11, 9.0.0–9.2.15, 10.0.0–10.1.4, and 10.2.0.

Apache Traffic Server's experimental tsmemcache plugin allows unauthenticated network read, write, and deletion of the shared proxy cache. Affects versions 8.0.0–8.1.11, 9.0.0–9.2.15, 10.0.0–10.1.4, and 10.2.0.

Apache Traffic Server allows request smuggling via HEAD requests that carry Content-Length or Transfer-Encoding headers. This affects versions 8.0.0 through 8.1.11, 9.0.0 through 9.2.15, 10.0.0 through 10.1.4, and 10.2.0.

Apache Traffic Server forwards malformed 302 responses that should be rejected as parse errors because the Transfer-Encoding: chunked carve-out bypasses the rejection path. A response that two peers can read differently is stored and served, allowing cache poisoning and response-framing desync.

Apache Traffic Server's experimental magick plugin lets an unauthenticated client control ImageMagick convert arguments in its default (unsigned) configuration. Affects versions 8.0.1–8.1.11, 9.0.0–9.2.15, 10.0.0–10.1.4, and 10.2.0.
