CVE-2026-0950

Spectra Gutenberg Blocks <= 2.19.17 - Unauthenticated Information Disclosure in Sensitive Data

5.3 Medium

The Spectra Gutenberg Blocks – Website Builder for the Block Editor plugin for WordPress is vulnerable to Information Disclosure in all versions up to, and including, 2.19.17. This is due to the plugin failing to check post_password_required() before rendering post excerpts in the render_excerpt() function and the uagb_get_excerpt() helper function. This makes it possible for unauthenticated attackers to read excerpts of password-protected posts by simply viewing any page that contains a Spectra Post Grid, Post Masonry, Post Carousel, or Post Timeline block.
