CVE-2026-81653: CWE-639 Authorization Bypass Through User-Controlled Key in Photo Gallery, Sliders, Proofing and Themes
The Photo Gallery, Sliders, Proofing and WordPress plugin before 4.5.0 does not verify that the user acting on an image owns the gallery it belongs to, allowing users granted its gallery-management capability by an administrator to delete, copy and re-tag any image on the site, including images in galleries belonging to other users.
AI Analysis
Technical Summary
CVE-2026-81653 is an authorization bypass vulnerability (CWE-639) in the Photo Gallery, Sliders, Proofing and Themes WordPress plugin versions prior to 4.5.0. The plugin fails to verify that a user acting on an image actually owns the gallery to which the image belongs. As a result, users granted gallery-management capabilities by an administrator can manipulate images across all galleries on the site, including those owned by other users. This flaw allows unauthorized deletion, copying, and re-tagging of images site-wide.
Potential Impact
Users with gallery-management privileges can bypass intended access controls and modify images in galleries they do not own. This can lead to unauthorized alteration or removal of images across the site, potentially impacting content integrity and user trust. There is no indication of active exploitation in the wild.
Mitigation Recommendations
Upgrade the Photo Gallery, Sliders, Proofing and Themes plugin to version 4.5.0 or later, where this authorization check issue is fixed. No other mitigation guidance is provided. Patch status is not explicitly confirmed in the input data, but the presence of a fixed version (4.5.0) implies an official fix is available.
