Version 13.4.1.1 fixes the heuristic mode by limiting exposure to the first five packets, and introduces a recrypt flag that fully prevents SRTP attacks when both mitigations are enabled.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:L/SI:L/SA:L","score":6.9},"cvss_v3":null,"cwes":["CWE-346"],"references":["https://github.com/EnableSecurity/advisories/tree/master/ES2025-01-rtpengine-improper-behavior-bleed-inject","https://github.com/sipwise/rtpengine/commits/rfuchs/security/","https://github.com/sipwise/rtpengine/releases/tag/mr13.4.1.1","https://www.openwall.com/lists/oss-security/2025/07/31/1","http://seclists.org/fulldisclosure/2025/Aug/1"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-53399","score":0.06294,"percentile":0.93597,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
