gst-plugins-bad1.0: A logic vulnerability was found in GStreamer's webrtcbin component
CVE-2026-14935 is fixed in 2 products on 1 platform, first by SUSE-SU-2026:3058-1, released July 15, 2026. It is not reported as exploited. Patch Radar priority: Routine.
A logic vulnerability was found in GStreamer's webrtcbin component. The _check_sdp_crypto() function contains an inverted boolean condition that causes it to accept remote SDP offers or answers that lack the required a=fingerprint attribute, while incorrectly rejecting those that include it. An attacker with the ability to intercept and modify WebRTC signaling messages could exploit this to bypass the SDP-level DTLS certificate fingerprint binding, weakening defenses against man-in-the-middle attacks on media streams.
