CVE-2024-2963

Description

The Pocket News Generator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings such as “Consumer Key” and “Access Token” in all versions up to, and including, 0.2.0 due to insufficient input sanitization and output escaping.

This only affects multi-site installations and installations where unfiltered_html has been disabled.
