Hi,

The following vulnerability was published for rtpengine.

CVE-2025-53399[0]:
| In Sipwise rtpengine before 13.4.1.1, an origin-validation error in
| the endpoint-learning logic of the media-relay core allows remote
| attackers to inject or intercept RTP/SRTP media streams via RTP
| packets (except when the relay is configured for strict source and
| learning disabled). 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.

I could not isolate the commits, but they might be related to the
MT#62735 fixes in the 'rfuchs/security' branch[3].

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
