CVE-2026-8976

Name of the Vulnerable Software and Affected Versions RSS Aggregator by Feedzy versions prior to 5.1.8

Description An authorization bypass exists because the plugin fails to properly verify if a user is authorized to perform specific actions. Authenticated attackers with contributor-level access or higher can create and execute RSS import jobs, force-delete all posts linked to any import job, clear import error logs, and enumerate post meta key names and taxonomy terms. This is possible because the required nonce is leaked to any user with the edit posts capability through the feedzyjs localized script injected into the block editor.

Recommendations Update to a version later than 5.1.7.
