{"schema":"threatline.record/2","record":{"id":"CVE-2026-106100","aliases":["GHSA-4ww4-68q3-h7g5"],"summary":"Payload: Field-level write access bypass in Payload on MongoDB","details":"### Impact\nA vulnerability in field-level access control could allow an authenticated user to modify fields they are not permitted to change on documents they can otherwise update.\n\nYou are affected if:\nPayload version < `3.87.0` (or a `4.0.0-canary` release before `4.0.0-canary.20`) using the MongoDB adapter (`@payloadcms/db-mongodb`) with any collection that relies on field-level access control to restrict writes under certain conditions.\n\nRelational adapters (Postgres, SQLite) are not affected.\n\n### Patches\nHandling of incoming field data has been hardened so field-level access control is enforced consistently.\n\nUsers should upgrade to `3.87.0` (or `4.0.0-canary.20` on the `4.x` line) or later.\n\n### Workarounds\nThere is no complete workaround. Upgrading to `3.87.0` (or `4.0.0-canary.20` on the `4.x` line) is recommended.","categories":["Databases"],"product":"@payloadcms/db-mongodb","vendor":"payloadcms","ecosystem":"npm","affected_ranges":[{"source":"GitHub Advisory
