Title
Improper handling of request URLs in Nextcloud Guests app allows guest users to bypass app allowlist

In affected versions users were able to load the first page of apps they were actually not allowed to access. Depending on the selection of apps installed this may present a permissions bypass. It is recommended that the Guests app is upgraded to 2.4.1, 2.5.1 or 3.0.1. There are no known workarounds for this vulnerability.
