Gutentools
Monthly
Stored Cross-Site Scripting in the Gutentools WordPress plugin (versions up to 1.1.3) allows authenticated attackers with Contributor-level access to inject arbitrary JavaScript into pages via the Post Slider block's block_id attribute. The vulnerability exploits insufficient input sanitization combined with a custom unescaping routine that reintroduces dangerous characters, enabling persistent payload execution whenever users access injected pages. This affects all installations using the plugin at or below version 1.1.3 and requires only low-privileged WordPress authentication.
