QuMagie Authorization Bypass Vulnerabilities

Authorization bypass in QNAP QuMagie versions prior to 2.9.1 allows remote unauthenticated attackers to manipulate user-controlled keys (IDOR-class flaw) and gain unintended privileges on the photo management application. The QNAP-issued advisory QSA-26-35 confirms the issue and ships a fix in 2.9.1; no public exploit identified at time of analysis, and the flaw is not currently listed in CISA KEV.

Unauthorized data access and action execution in QNAP QuMagie versions prior to 2.9.0 allows remote attackers to bypass authorization checks over the network without authentication. The CVSS 4.0 score of 8.7 reflects high confidentiality impact with low attack complexity and no privileges required, though no public exploit identified at time of analysis and KEV listing is absent.
