The ShortPixel Image Optimizer WordPress plugin contains a Stored Cross-Site Scripting (XSS) vulnerability in versions up to and including 6.4.3, affecting the getEditorPopup() function and media-popup.php template. Authenticated attackers with Author-level permissions can inject arbitrary JavaScript into attachment post titles via the REST API, which executes when administrators open the ShortPixel AI editor popup for the poisoned attachment. This vulnerability has a CVSS score of 5.4 (moderate severity) and requires user interaction from a higher-privileged administrator to trigger, limiting its immediate exploitation scope but still presenting a meaningful privilege escalation risk in multi-author WordPress environments.
