Summary
The PhotoSwipe WordPress plugin through 4.1.1.1 uses the title attribute of author-supplied link markup as a lightbox caption written into the page DOM without escaping. An authenticated user with Author-level access can store a JavaScript payload that executes in any visitor's browser, including an administrator, who clicks the link.
Risk Assessment
An attacker can inject a malicious script that executes in visitors' browsers, potentially leading to session theft, redirects, or data theft.
Recommendation
Update the PhotoSwipe plugin to a version newer than 4.1.1.1 if a fix is available.

See all- CVE-2026-14300High
The miniOrange Social Login and Register WordPress plugin before 7.8.0 does not bind the one-time code used for optional email verification to the account it was issued for.

- CVE-2026-13690High
The UsersWP WordPress plugin before 1.2.67 does not validate the selected authentication provider in its two-factor login handler. This allows an attacker who already knows a user's credentials to bypass the second authentication factor and log in as that user.
- CVE-2026-11351Medium

Original NVD description (English source)
The PhotoSwipe WordPress plugin through 4.1.1.1 uses the title attribute of author-supplied link markup as a lightbox caption that is written into the page DOM without escaping. Because the title attribute survives the post-content sanitization applied to users who lack the unfiltered_html capability, an authenticated user with Author-level access can store a JavaScript payload that executes in the browser of any visitor, including an administrator, who clicks the link.
