CVE-2026-19943 (GCVE-0-2026-19943)
Vulnerability from cvelistv5
Published
2026-08-25 03:27
Modified
2026-08-25 18:12
Severity ?
6.4 (Medium) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N
CWE
  • CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Summary
The Gutenverse – WordPress Blocks, Page Builder & Site Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'titleTag' Block Attribute in all versions up to, and including, 4.0.2 due to insufficient input sanitization and output escaping. 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. The malicious titleTag value survives wp_kses_post on save because it is stored inside a block-comment delimiter and the live HTML is only synthesized at render time by do_blocks(), meaning the payload also fires in administrator and editor sessions during post preview.

CVE-2026-3001 (GCVE-0-2026-3001)
Vulnerability from cvelistv5
Published
2026-05-27 07:45
Modified
2026-05-27 10:28
Severity ?
6.1 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
CWE
  • CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Summary
The Gutenverse plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in all versions up to, and including, 3.4.6 due to insufficient input sanitization and output escaping. Specifically, the `render_content()` method in `class-search-result-title.php` outputs the value of `get_query_var('s')` directly into the page HTML without applying `esc_html()` or any other escaping function. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages via a crafted URL that execute if a user clicks the link, provided the `gutenverse/search-result-title` block is present on the site's search results template.
