What is CVE-2026-89003?

The WPeMatico RSS Feed Fetcher plugin for WordPress is vulnerable due to inadequate capability checks when processing user-supplied URLs. This flaw allows users with contributor-level access and higher permissions to manipulate the plugin into making unauthorized requests to internal servers, thereby retrieving potentially sensitive data. Without appropriate validation controls, the plugin becomes a risk for exposing internal network information, prompting immediate action from site administrators to mitigate the issue by updating to the latest patched version.

Affected Version(s)

WPeMatico RSS Feed Fetcher 0 < 2.8.27
