{"id":"CVE-2026-77322","summary":"SIPGO: DoS via unvalidated WebSocket frame length","details":"SIPGO is a library for writing SIP services in the GO language. 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.","aliases":["GHSA-8h6x-h86x-75wh"],"modified":"2026-09-24T03:45:16.214353970Z","published":"2026-09-22T19:52:12.441Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-789"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77322.json"},"references":[{"type":"WEB","url":"https://github.com/emiago/sipgo/releases/tag/v1.4.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77322.json"},{"type":"ADVISORY","url":"https://github.com/emiago/sipgo/security/advisories/GHSA-8h6x-h86x-75wh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77322"},{"type":"FIX","url":"https://github.com/emiago/sipgo/commit/769e4bc958376e2363566c8f7042202b410becdc"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/emiago/sipgo","events":[{"introduced":"0"},{"fixed":"769e4bc958376e2363566c8f7042202b410becdc"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.4.3"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.4.2","v1.4.1","v1.4.0","v1.3.1","v1.3.0","v1.2.1","v1.2.0","v1.1.2","v1.1.1","v1.1.0","v1.0.2","v1.0.1","v1.0.0","v1.0.0-beta-4","v1.0.0-beta-3","v1.0.0-beta-2","v1.0.0-beta-1","v1.0.0-alpha-2","v1.0.1-alpha","v1.0.0-alpha-1","v1.0.0-alpha","v0.33.0","v0.32.1","v0.32.0","v0.31.0","v0.30.0","v0.29.0","v0.28.0","v0.27.1","v0.27.0","v0.26.1","v0.26.0","v0.25.1","v0.25.0","v0.24.1","v0.24.0","v0.23.0","v0.22.1","v0.22.0","v0.21.0","v0.20.0","v0.19.0","v0.18.0","v0.17.1","v0.17.0","v0.16.1","v0.16.0","v0.15.2","v0.15.1","v0.15.0","v0.14.0","v0.13.1","v0.13.0","v0.12.1","v0.12.0","v0.11.1","v0.11.0","v0.10.1","v0.10.0","v0.9.0","v0.8.0","v0.7.2","v0.7.1","v0.7.0","v0.6.0","v0.5.0","v0.4.0","v0.3.0","v0.2.0","v0.1.2","v0.1.1","v0.1.0","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-77322.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
