Prior to 1.11.2, dtls_state_setup() compared a peer certificate with the SDP a=fingerprint only when FreeSWITCH was the DTLS client, not when it held the DTLS server role. An unauthenticated peer able to reach the negotiated media port could complete the DTLS-SRTP handshake with an unrelated certificate, obtain the leg's SRTP keys, decrypt and inject media, and displace the legitimate endpoint; on ICE-enabled legs the peer also needs the connectivity-check credentials from SDP, which generally requires signaling visibility or a position on its path. WebRTC and SIP DTLS-SRTP legs are affected whenever the peer selects the active role, while FreeSWITCH client-role handshakes already perform fingerprint validation. Version 1.11.2 introduces the remediation, which requires rtp_dtls_client_cert_verify_mode=fingerprint."}],"id":"CVE-2026-116789","lastModified":"2026-11-10T18:40:46.283","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"HIGH","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":7.4,"baseSeverity":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"HIGH","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"exploitabilityScore":2.2,"impactScore":5.2,"source":"security-advisories@github.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-116789","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","timestamp":"2026-11-09T22:43:25.863230Z","version":"2.0.3"}}]},"published":"2026-11-05T20:17:46.397","references":[{"source":"security-advisories@github.com","tags":["Patch"],"url":"https://github.com/signalwire/freeswitch/commit/ea74c0acb8b85c5fc50158cd592a1b80c4edf6a6"},{"source":"security-advisories@github.com","tags":["Release Notes"],"url":"https://github.com/signalwire/freeswitch/releases/tag/v1.11.2"},{"source":"security-advisories@github.com","tags":["Vendor Advisory","Mitigation"],"url":"https://github.com/signalwire/freeswitch/security/advisories/GHSA-8ghv-ccjr-4cx9"}],"sourceIdentifier":"security-advisories@github.com","vulnStatus":"Analyzed","weaknesses":[{"description":[{"lang":"en","value":"CWE-295"},{"lang":"en","value":"CWE-300"}],"source":"security-advisories@github.com","type":"Secondary"}]}
