{"id":"GHSA-fpww-c55p-cjv6","summary":"Payload: Polymorphic join queries could disclose hidden fields","details":"### Impact\n\nA user with query access could use polymorphic join filters to infer hidden or read-restricted field values, including password-reset tokens.\n\nYou are affected if:\n\n- You use an affected Payload version.\n- Users can query a collection with a polymorphic join to sensitive fields.\n\n### Patches\n\nUsers should upgrade Payload packages to `\u003e= 3.90.0` or `\u003e= 4.0.0-canary.34`.\n\n### Workarounds\n\nThere is no complete workaround. Restricting read access to sensitive collections reduces exposure but does not replace upgrading.","aliases":["CVE-2026-105847"],"modified":"2026-10-06T16:15:05.075692397Z","published":"2026-10-06T16:09:04Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-10-06T16:09:04Z","nvd_published_at":null,"cwe_ids":["CWE-200","CWE-639"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/payloadcms/payload/security/advisories/GHSA-fpww-c55p-cjv6"},{"type":"WEB","url":"https://github.com/payloadcms/payload/commit/caa3f69b5aecc6e7c2b459ed87972cbca9f33ee5"},{"type":"PACKAGE","url":"https://github.com/payloadcms/payload"},{"type":"WEB","url":"https://github.com/payloadcms/payload/releases/tag/v3.90.0"}],"affected":[{"package":{"name":"payload","ecosystem":"npm","purl":"pkg:npm/payload"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.0.0"},{"fixed":"3.90.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-fpww-c55p-cjv6/GHSA-fpww-c55p-cjv6.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.34"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-fpww-c55p-cjv6/GHSA-fpww-c55p-cjv6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
