## What is CVE-2026-0950?

CVE-2026-0950 is a medium-severity vulnerability in brainstormforce Spectra Gutenberg Blocks – Website Builder for the Block Editor, published on 3 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)
