CVE-2026-109936 (GCVE-0-2026-109936)

Vulnerability from nvd – Published: 2026-10-23 06:00 – Updated: 2026-10-23 10:45

Title

Otter Blocks < 3.2.8 - Unauthenticated Stored XSS via Dynamic Content Render Filter

Summary

The Otter Blocks WordPress plugin before 3.2.8 does not correctly bound a pattern it uses to rewrite its dynamic-content tokens while rendering blocks, so the pattern can consume the quote that closes an HTML attribute and pull adjacent unescaped data into the markup as new attributes. This allows unauthenticated users to achieve stored Cross-Site Scripting that executes in the browser of any visitor who views an affected page, including a logged-in administrator.

Severity

7.5 (High)

CVE-2026-109936 (GCVE-0-2026-109936)

Vulnerability from cvelistv5 – Published: 2026-10-23 06:00 – Updated: 2026-10-23 10:45

Title

Otter Blocks < 3.2.8 - Unauthenticated Stored XSS via Dynamic Content Render Filter

Summary

The Otter Blocks WordPress plugin before 3.2.8 does not correctly bound a pattern it uses to rewrite its dynamic-content tokens while rendering blocks, so the pattern can consume the quote that closes an HTML attribute and pull adjacent unescaped data into the markup as new attributes. This allows unauthenticated users to achieve stored Cross-Site Scripting that executes in the browser of any visitor who views an affected page, including a logged-in administrator.

Severity

7.5 (High)

Otter Blocks 3.1.1 - 3.2.7 - Unauthenticated Non-Public Content Disclosure via REST API

Summary

The Otter Blocks WordPress plugin before 3.2.8 does not correctly determine whether a post is publicly readable before returning its data through a REST API endpoint, treating any post with the published status as public, allowing unauthenticated users to read manual excerpts of password-protected posts, the content and titles of non-public post types, and, on WooCommerce sites, coupon codes and their descriptions.
