Categories Images, CVE-2026-2505

CVE, Research URL: CVE-2026-2505
Home page URL: Security reports for Categories Images
Application: Categories Images
Published on: Apr 18, 2026
Research Description: The Categories Images plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.3.1, via the 'z_taxonomy_image' shortcode. This is due to the shortcode rendering path passing attacker-controlled class input into a fallback image builder that concatenates HTML attributes without proper escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts that execute when users interact with the injected frontend page via the 'class' shortcode attribute.
Affected versions: max 3.3.2.
Status: vulnerable
