Payload is a free and open source headless content management system. In versions before 3.88.0 and canary versions before 4.0.0-canary.27, an untrusted user who can query a readable collection, control its sorting, and select a protected field as the sort parameter can infer limited information about field values the user cannot read. This issue is fixed in versions 3.88.0 and 4.0.0-canary.27.

Affected: npm: payload

### Impact Under certain conditions, sorting readable records could reveal limited information about fields the requester was not permitted to read.

You are affected if untrusted users can query a collection, control its sorting, and sort by protected fields.

### Patches Payload now applies field-level access checks to sort fields before executing queries.

Users should upgrade to `>= 3.88.0` or `>= 4.0.0-canary.27`.

### Workarounds Upgrading is recommended. Until then, prevent untrusted users from controlling sort parameters or restrict their access to affected collections.
