Payload is a free and open source headless content management system. In @payloadcms/db-mongodb versions before 3.87.0 and canary versions before 4.0.0-canary.20, an authenticated user who can update a document can modify fields that field-level write access control does not permit that user to change. The Postgres and SQLite adapters are not affected. This issue is fixed in versions 3.87.0 and 4.0.0-canary.20.

- GHSA-4ww4-68q3-h7g5Payload: Field-level write access bypass in Payload on MongoDB2026-10-07ghsa · osvUS
### Impact A 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. You are affected if: Payload 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. Relational adapters (Postgres, SQLite) are not affected. ### Patches Handling of incoming field data has been hardened so field-level access control is enforced consistently. Users should upgrade to `3.87.0` (or `4.0.0-canary.20` on the `4.x` line) or later. ### Workarounds There is no complete workaround. Upgrading to `3.87.0` (or `4.0.0-canary.20` on the `4.x` line) is recommended.
