{"id":"CVE-2025-49140","aliases":["GHSA-f26w-gh5m-qq77","GO-2025-3748"],"url":"https://o3.security/vulnerability/CVE-2025-49140","summary":"Pion Interceptor's improper RTP padding handling allows remote crash for SFU users (DoS)","details":"Pion Interceptor is a framework for building RTP/RTCP communication software. Versions v0.1.36 through v0.1.38 contain a bug in a RTP packet factory that can be exploited to trigger a panic with Pion based SFU via crafted RTP packets, This only affect users that use pion/interceptor. Users should upgrade to v0.1.39 or later, which validates that: `padLen > 0 && padLen <= payloadLength` and return error  on overflow, avoiding panic. If upgrading is not possible, apply the patch from the pull request manually or drop packets whose P-bit is set but whose padLen is zero or larger than the remaining payload.","published":"2025-06-09T21:13:12.388Z","modified":"2026-08-12T03:51:08.630919572Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00493,"percentile":0.41187,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/pion/interceptor","fixedVersion":"0.1.39"}],"fix":{"url":"https://github.com/pion/interceptor/commit/fa5b35ea867389cec33a9c82fffbd459ca8958e5","label":"pion/interceptor@fa5b35e"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/49xxx/CVE-2025-49140.json"},{"type":"ADVISORY","url":"https://github.com/pion/interceptor/security/advisories/GHSA-f26w-gh5m-qq77"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-49140"},{"type":"REPORT","url":"https://github.com/pion/webrtc/issues/3148"},{"type":"FIX","url":"https://github.com/pion/interceptor/commit/fa5b35ea867389cec33a9c82fffbd459ca8958e5"},{"type":"FIX","url":"https://github.com/pion/interceptor/pull/338"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:08.630919572Z"}}
