Summary

Payload from 3.40.0 before 3.88.0 and its canary releases from 4.0.0-canary.0 before 4.0.0-canary.27 do not validate a redirect URL parameter. An attacker can craft a link that sends a guest user to an untrusted destination after the authentication flow completes (CWE-601). The victim must interact with the crafted link, and @payloadcms/next from 3.31.0 before 3.88.0 and from 4.0.0-canary.0 before 4.0.0-canary.27 is affected too.

Description from the CNA

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.
