Sources and claim methodology

Upstream source description

Shiori contains a privilege escalation vulnerability in the account update endpoint that allows authenticated users to modify the owner field without authorization checks. Attackers can escalate to administrator by submitting a crafted PATCH request with owner: true, then re-authenticate to obtain an admin JWT token granting full system access.
