Résumé
Vikunja Vulnerable to Link Share Hash Disclosure via ReadAll Endpoint Enables Permission Escalation
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.2, the LinkSharing.ReadAll() method allows link share authenticated users to list all link shares for a project, including their secret hashes. While LinkSharing.CanRead() correctly blocks link share users from reading individual shares via ReadOne, the ReadAllWeb handler bypasses this check by never calling CanRead(). An attacker with a read-only link share can retrieve hashes for write or admin link shares on the same project and authenticate with them, escalating to full admin access. Version 2.2.2 patches the issue.
