CVE-2026-2509

Beschreibung

The Page Builder: Pagelayer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Button widget-s Custom Attributes field in all versions up to, and including, 2.0.8. This is due to an incomplete event handler blocklist in the -pagelayer_xss_content- XSS filtering function, which blocks common, but not all, event handlers. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
