Description
CVE-2026-13605 is a cross-site scripting (XSS) vulnerability in the PhotoSwipe WordPress plugin up to version 4.1.1.1. It arises because the plugin uses the title attribute of author-supplied link markup as a lightbox caption without proper escaping. This attribute bypasses post-content sanitization for users without unfiltered_html capability, allowing an authenticated user with Author-level access to inject JavaScript payloads. These payloads execute in the browsers of visitors, including administrators, who click the malicious link.
