Technical Analysis

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a reflected XSS vulnerability in plugin/Gallery/view/Category.php when SubCategorys is enabled. The getBackURL parameter is echoed into an href attribute without HTML encoding, enabling injection of malicious scripts that execute in visitors' browsers upon interaction with the Back control.

Potential Impact

Successful exploitation allows attackers to execute arbitrary scripts in the context of the victim's browser session when they interact with the Back control. This can lead to limited confidentiality and integrity impacts such as session hijacking or content manipulation. The CVSS score of 5.3 reflects a medium severity with network attack vector, low complexity, no privileges required, and user interaction needed.

Mitigation Recommendations

No official patch or remediation information is provided in the input data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when interacting with the Back control in the affected plugin and consider disabling the SubCategorys feature if feasible.
