Prior to 1.0.0-rc.16, the Grav API plugin JwtAuthenticator::extractBearerToken() accepts a JWT from the token URL query parameter on every /api/v1 route, including state-changing endpoints. Request URLs consequently expose valid access tokens through Apache, proxy, and CDN logs, browser history, and Referer headers, allowing a party with access to those records to reuse the token with the owner's API privileges. This issue is fixed in version 1.0.0-rc.16.","published":"2026-08-19T16:18:38.013","modified":"2026-08-19T16:18:38.013","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/getgrav/grav-plugin-api/commit/56ae2ca3bf36c8299a4b3d376c6a20e8c0ed5ba9","label":"getgrav/grav-plugin-api@56ae2ca"},"references":[{"type":"WEB","url":"https://github.com/getgrav/grav-plugin-api/commit/56ae2ca3bf36c8299a4b3d376c6a20e8c0ed5ba9"},{"type":"WEB","url":"https://github.com/getgrav/grav-plugin-api/releases/tag/1.0.0-rc.16"},{"type":"WEB","url":"https://github.com/getgrav/grav/security/advisories/GHSA-4hpj-wmpw-ghwq"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T16:18:38.013"}}
