# WPeMatico RSS Feed Fetcher: contributor can plant script that runs for admins

Link for people: https://infrastack.ai/live/CVE-2026-120573 (this .md is for agents)

The WPeMatico RSS Feed Fetcher WordPress plugin up to and including 2.9.1 does not sanitize the post_category parameter. An authenticated contributor can store a script that runs in the browser of any editor or administrator who opens the WPeMatico campaigns list.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

The WPeMatico RSS Feed Fetcher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'post_category' parameter in all versions up to, and including, 2.9.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The injected payload is persisted in post meta as campaign_data, bypassing wp_kses sanitization, and executes in the browser session of any user with edit_posts — including Administrators — who opens the WPeMatico campaigns list screen.
