The FFI API is disabled by default by a build-time feature flag.\n\nquiche 0.29.2 is the earliest version containing the fix for this issue.","state":0,"publishedAt":"2026-06-19T22:10:29+00:00","modifiedAt":"2026-06-19T22:26:27.22127+00:00","affected":[{"ecosystem":"crates.io","name":"quiche","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0.20.0"},{"kind":"fixed","version":"0.29.2"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/cloudflare/quiche/security/advisories/GHSA-mh64-ph39-mrc9","https://nvd.nist.gov/vuln/detail/CVE-2026-11941","https://github.com/cloudflare/quiche"],"sourceUrl":"https://github.com/advisories/GHSA-mh64-ph39-mrc9","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-mh64-ph39-mrc9","identifiers":["GHSA-mh64-ph39-mrc9","CVE-2026-11941"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
