Description

Impact

An attacker can submit a request to a specific endpoint that permits collection documents to be updated regardless of access control and field level access control.

You are affected if:

  • You are configuring orderable: true with any collection or join field.

Patches

In the patched version access control is properly enforced.

Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for payload, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update payload to 3.90.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f7hx-52q9-hcrf is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Frequently Asked Questions

## Impact An attacker can submit a request to a specific endpoint that permits collection documents to be updated regardless of access control and field level access control. **You are affected if:** - You are configuring `orderable: true` with any collection or join field. ## Patches In the patched version access control is properly enforced. Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.
