Disclosure summary
### 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.
