Attackers can access the surviving share link to retrieve new unrelated content uploaded to the same path without authentication.
LOW 2.3EPSS 0.28%
Does this matter?
Lower severity and a low EPSS score (0.28%). Track it; it rarely justifies an emergency change on its own.
Description
File Browser versions from 2.63.6 through 2.63.23 fail to clean up public share links when a privileged user deletes another user's shared file. Attackers can access the surviving share link to retrieve new unrelated content uploaded to the same path without authentication.
