Technical details
Stored cross-site scripting (XSS) in the RSS Feed catalog widget due to insufficient input sanitization and output escaping on the title and description fields. The plugin's escaping logic intentionally excludes raw content from sanitization, and XML entity-encoded payloads in feed item titles are decoded before reaching the vulnerable sink, allowing unauthenticated attackers to inject scripts that persist server-side and execute in users' browsers when they access pages displaying the widget.
