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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-789"],"references":["https://github.com/emiago/sipgo/commit/769e4bc958376e2363566c8f7042202b410becdc","https://github.com/emiago/sipgo/releases/tag/v1.4.3","https://github.com/emiago/sipgo/security/advisories/GHSA-8h6x-h86x-75wh","https://github.com/emiago/sipgo/security/advisories/GHSA-8h6x-h86x-75wh"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-77322","score":0.00609,"percentile":0.49185,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8h6x-h86x-75wh","url":"https://osv.dev/vulnerability/GHSA-8h6x-h86x-75wh","summary":"SIPGO: DoS via unvalidated WebSocket frame length","modified":"2026-10-01T20:56:11.724309977Z","packages":[{"ecosystem":"Go","name":"github.com/emiago/sipgo","purl":"pkg:golang/github.com/emiago/sipgo","ranges":["<1.4.3"],"fixed":["1.4.3"]}]},{"id":"GO-2026-6559","url":"https://osv.dev/vulnerability/GO-2026-6559","summary":"SIPGO: DoS via unvalidated WebSocket frame length in github.com/emiago/sipgo","modified":"2026-10-01T20:45:13.179335385Z","packages":[{"ecosystem":"Go","name":"github.com/emiago/sipgo","purl":"pkg:golang/github.com/emiago/sipgo","ranges":["<1.4.3"],"fixed":["1.4.3"]}]}],"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).
