What is CVE-2026-2509?
CVE-2026-2509 is a medium-severity cross-site scripting vulnerability in softaculous Page Builder: Pagelayer – Drag and Drop website builder, published on 8 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-79
