CVE-2026-1216

Name of the Vulnerable Software and Affected Versions RSS Aggregator plugin for WordPress versions up to and including 5.0.10

Description The RSS Aggregator plugin for WordPress is susceptible to Reflected Cross-Site Scripting. This is due to insufficient input sanitization and output escaping on user-supplied attributes within the template parameter. This allows unauthenticated attackers to inject arbitrary web scripts into pages. Successful exploitation requires tricking a user into performing an action, such as clicking a link. The vulnerable parameter is template.

Recommendations Update the RSS Aggregator plugin to a version newer than 5.0.10.
