Payload: Untrusted redirect URL parameter exploit

  • Disclosed: 06.10.2026
  • Updated: 11.10.2026 10:22

Impact

Under certain conditions, an attacker can craft a redirect link that sends a guest user to an untrusted destination after authenticating.

Patches

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

Workarounds

Upgrading is recommended. Until then, remove user-controlled redirect values from authentication flows or restrict them to known local paths.
