An exposed key grants the target account’s permissions until rotated or disabled.\n\nYou are affected if:\n\n- An authentication collection enables `useAPIKey`.\n- Users have read access to other user documents containing active API keys.\n\n### Patches\n\nUsers should upgrade payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.\n\n### Workarounds\n\nDisable `useAPIKey` or restrict users to reading only their own authentication document. Rotate any API key that may have been exposed.","published":"2026-10-06T16:09:49.402Z","modified":"2026-10-16T02:47:41.889467345Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"payload","fixedVersion":"3.90.0"},{"ecosystem":"npm","name":"payload","fixedVersion":"4.0.0-canary.34"}],"fix":{"url":"https://github.com/payloadcms/payload/commit/880d2e900be22cd66a9e939f2b3e702fa413180f","label":"payloadcms/payload@880d2e9"},"references":[{"type":"WEB","url":"https://github.com/payloadcms/payload/releases/tag/v3.90.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/105xxx/CVE-2026-105849.json"},{"type":"ADVISORY","url":"https://github.com/payloadcms/payload/security/advisories/GHSA-238x-w2j9-gwwr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105849"},{"type":"FIX","url":"https://github.com/payloadcms/payload/commit/880d2e900be22cd66a9e939f2b3e702fa413180f"},{"type":"PACKAGE","url":"https://github.com/payloadcms/payload"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-16T02:47:41.889467345Z"}}
