CVE-2026-0950: CWE-200 Exposure of Sensitive Information to an Unauthorized Actor in brainstormforce Spectra Gutenberg Blocks – Website Builder for the Block Editor
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.
AI Analysis
Technical Summary
The Spectra Gutenberg Blocks plugin for WordPress fails to check the `post_password_required()` condition before rendering excerpts in the `render_excerpt()` and `uagb_get_excerpt()` functions. This flaw allows unauthenticated attackers to access excerpts from password-protected posts when these posts are displayed via Spectra Post Grid, Post Masonry, Post Carousel, or Post Timeline blocks. The vulnerability is classified as CWE-200 (Exposure of Sensitive Information) and affects all versions up to 2.19.17. The CVSS 3.1 base score is 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), reflecting network attack vector, low complexity, no privileges or user interaction required, and limited confidentiality impact.
Potential Impact
An unauthenticated attacker can read excerpts of password-protected posts that should be restricted, leading to partial exposure of sensitive content. This compromises the confidentiality of information intended to be protected by post passwords. There is no impact on integrity or availability reported. No known exploits are currently in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider avoiding use of the affected blocks (Post Grid, Post Masonry, Post Carousel, Post Timeline) with password-protected posts or restrict access to pages containing these blocks. Monitor official Brainstormforce communications for updates and apply patches promptly once released.
