{"id":"GHSA-w84c-53h3-mc2g","summary":"Payload: Untrusted redirect URL parameter exploit","details":"### Impact\nUnder certain conditions, an attacker can craft a redirect link that sends a guest user to an untrusted destination after authenticating.\n\n### Patches\nUsers should upgrade Payload packages to `\u003e= 3.88.0` or `\u003e= 4.0.0-canary.27`.\n\n### Workarounds\nUpgrading is recommended. Until then, remove user-controlled redirect values from authentication flows or restrict them to known local paths.","aliases":["CVE-2026-105846"],"modified":"2026-10-06T16:15:05.069813584Z","published":"2026-10-06T16:09:13Z","database_specific":{"github_reviewed_at":"2026-10-06T16:09:13Z","nvd_published_at":null,"cwe_ids":["CWE-601"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/payloadcms/payload/security/advisories/GHSA-w84c-53h3-mc2g"},{"type":"WEB","url":"https://github.com/payloadcms/payload/commit/a742140ab4fca3160f7f83e9e7d996552ffc3b5a"},{"type":"PACKAGE","url":"https://github.com/payloadcms/payload"},{"type":"WEB","url":"https://github.com/payloadcms/payload/releases/tag/v3.88.0"}],"affected":[{"package":{"name":"payload","ecosystem":"npm","purl":"pkg:npm/payload"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.40.0"},{"fixed":"3.88.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-w84c-53h3-mc2g/GHSA-w84c-53h3-mc2g.json"}},{"package":{"name":"payload","ecosystem":"npm","purl":"pkg:npm/payload"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.0.0-canary.0"},{"fixed":"4.0.0-canary.27"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-w84c-53h3-mc2g/GHSA-w84c-53h3-mc2g.json"}},{"package":{"name":"@payloadcms/next","ecosystem":"npm","purl":"pkg:npm/%40payloadcms/next"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.31.0"},{"fixed":"3.88.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-w84c-53h3-mc2g/GHSA-w84c-53h3-mc2g.json"}},{"package":{"name":"@payloadcms/next","ecosystem":"npm","purl":"pkg:npm/%40payloadcms/next"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.0.0-canary.0"},{"fixed":"4.0.0-canary.27"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-w84c-53h3-mc2g/GHSA-w84c-53h3-mc2g.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
