## What is CVE-2026-12865?

CVE-2026-12865 is a high-severity cross-site scripting vulnerability in Unknown Photo Gallery by 10Web, published on 2 Sep 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

The Photo Gallery by 10Web  WordPress plugin before 1.8.44 does not escape two request parameters before reflecting them into input-attribute values on its admin pages (one on the Shortcode page, one on the Galleries/Albums list page), so an unauthenticated attacker can craft a link that, when opened by a logged-in administrator (or, for the first sink, a contributor), executes arbitrary JavaScript in the victim's authenticated session via an auto-firing onfocus handler. The Galleries/Albums sink renders only when the site has more than 20 galleries/albums (the normal state of a populated install).

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
