The forgot-password flow also enforces a configurable minimum interval between reset emails, which defaults to 15 seconds.\n\nUsers should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.","published":"2026-10-06T16:46:31.069Z","modified":"2026-10-08T02:50:32.203746792Z","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/1c46204a73a0a9f988a80c52690eee5a4ada3cf1","label":"payloadcms/payload@1c46204"},"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-2026-105866.json"},{"type":"ADVISORY","url":"https://github.com/payloadcms/payload/security/advisories/GHSA-v5gf-vpjc-pc7w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-105866"},{"type":"FIX","url":"https://github.com/payloadcms/payload/commit/1c46204a73a0a9f988a80c52690eee5a4ada3cf1"},{"type":"PACKAGE","url":"https://github.com/payloadcms/payload"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-08T02:50:32.203746792Z"}}
