CVE, Research URL: CVE-2026-3876
Home page URL: Security reports for Prismatic
Application: Prismatic
Date: Apr 16, 2026
Research Description: The Prismatic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'prismatic_encoded' pseudo-shortcode in all versions up to, and including, 3.7.3. This is due to insufficient input sanitization and output escaping on user-supplied attributes within the 'prismatic_decode' function. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page by submitting a comment containing a crafted 'prismatic_encoded' pseudo-shortcode.
Affected versions: max 3.7.4.
Status: vulnerable

CVE, Research URL: CVE-2021-24408
Home page URL: Security reports for Prismatic
Application: Prismatic
Date: Jul 13, 2021
Research Description: The Prismatic WordPress plugin before 2.8 does not sanitise or validate some of its shortcode parameters, allowing users with a role as low as Contributor to set Cross-Site payload in them.

Affected versions: max 2.8.
Status: vulnerable
