Contest Gallery

Sensitive data exposure in the Contest Gallery WordPress plugin (versions <= 28.1.7) allows authenticated subscribers to access confidential information they are not authorized to view. The vulnerability stems from insufficient access control over data retrieval endpoints within the plugin, permitting low-privileged WordPress users to read sensitive data with high confidentiality impact. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog, but the low complexity and remote exploitability make it a credible risk for WordPress sites with open subscriber registration.

Unauthenticated integrity-impacting input validation failure in the Contest Gallery WordPress plugin affects all versions up to and including 28.1.7, allowing network-accessible attackers with no privileges to perform unauthorized write-class operations against the plugin. The CVSS vector confirms the unauthenticated, low-complexity attack path (AV:N/AC:L/PR:N/UI:N) with low integrity impact and unchanged scope. No public exploit code and no CISA KEV listing have been identified at time of analysis, placing this in a monitor-and-patch posture rather than emergency response.

Cross-site scripting in the Contest Gallery WordPress plugin (versions <= 28.1.6) can be triggered by a subscriber-level authenticated user, injecting malicious scripts that execute in the browsers of higher-privileged users such as administrators. The CVSS Scope:Changed metric confirms the payload escapes the subscriber's privilege boundary and impacts other user sessions. No public exploit code or CISA KEV listing has been identified at time of analysis, but the low attack complexity and broad WordPress ecosystem deployment surface make this a meaningful risk for any site accepting subscriber registrations.

Unauthenticated SQL injection in the Contest Gallery WordPress plugin (versions ≤28.1.6) allows remote attackers to inject arbitrary SQL into backend database queries without credentials or user interaction.
