Mô tả

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.

Mô tả của NVD

Payload is a free and open source headless content management system. In versions from 3.40.0 before 3.88.0 and canary versions before 4.0.0-canary.27, an attacker can craft a redirect URL parameter that sends a guest user to an untrusted destination after the authentication flow completes. This issue is fixed in versions 3.88.0 and 4.0.0-canary.27.
