go-shiori/shiori

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.

A lack of rate limiting in the login page of shiori v1.7.4 and below allows attackers to bypass authentication via a brute force attack.
