## What is CVE-2026-103875?

CVE-2026-103875 is a medium-severity vulnerability in dglingren Media Library Assistant, published on 29 Oct 2026. 

### Official description

The Media Library Assistant plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'search-string' parameter in all versions up to, and including, 3.42 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploitation requires the targeted site to have a publicly accessible page containing an [mla_gallery] shortcode configured with a pagination output mode and an mla_link_href template that reflects a {+request:...+} token, along with enough attachments to trigger pagination.

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