The wpdevart Responsive Image Gallery, Gallery Album plugin suffers from a CWE-79 reflected cross-site scripting vulnerability (CVE-2024-30550) in versions up to 2.0.3. This occurs because the plugin does not properly neutralize user input during web page generation, allowing malicious scripts to be reflected back to users. The vulnerability has a CVSS 3.1 score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts to confidentiality, integrity, and availability at a low level. No vendor advisory or patch is currently available, and the plugin is not a cloud service.

Successful exploitation of this vulnerability can lead to reflected XSS attacks, which may allow attackers to execute arbitrary scripts in the context of the affected site. This can result in partial compromise of user confidentiality, integrity, and availability. The scope is changed, meaning the attack can affect components beyond the vulnerable plugin itself. However, no known exploits have been reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling or limiting use of the affected plugin to reduce exposure. Employing web application firewalls (WAFs) that can detect and block reflected XSS payloads may provide temporary mitigation. Monitor vendor channels for updates and apply patches promptly once available.
