CVE-2026-61463 Details
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.
A privilege escalation vulnerability has been identified in Shiori versions prior to 1.8.0. The issue resides in the account update endpoint, where authenticated users can modify the owner field without proper authorization checks. This vulnerability allows users to escalate their privileges to administrator by sending a PATCH request with owner set to true.
