Prior to 1.4.3, WSConnection.Read in sip/transport_ws.go creates a wsutil.Reader without setting MaxFrameSize, allowing NextFrame to accept a client-controlled header.Length before ParseMaxMessageLength is applied. An unauthenticated WS or WSS peer can send a frame header declaring an extremely large payload, causing an oversized allocation or a makeslice length panic before the payload is read and crashing or exhausting memory in the server process. This issue is fixed in version 1.4.3.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-77322)\n\nAffected packages:\n\n- `github.com/emiago/sipgo <= 1.4.2`\n\nPatched in:\n\n- `github.com/emiago/sipgo 1.4.3`\n\nSource: https://github.com/advisories/GHSA-8h6x-h86x-75wh","depth":"midnight","depthScore":53,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":209704,"id":"CVE-2026-77322","ts":1790177218561,"field":"exploit_available","old":"false","new":"true"}]}
