CVE-2026-4032 is a stored cross-site scripting vulnerability in the CodeColorer WordPress plugin (versions up to 0.10.1). The issue is due to improper neutralization of input in the 'class' parameter of the 'cc' comment shortcode, which does not properly sanitize or escape user input. This allows unauthenticated attackers to inject malicious scripts into comments that execute in the context of users viewing the affected pages. Successful exploitation depends on comments being enabled and guest comments being allowed on the WordPress site.

An attacker can inject arbitrary web scripts that execute in the browsers of users who view the compromised pages, potentially leading to session hijacking, defacement, or other client-side attacks. The vulnerability requires no authentication but depends on site configuration allowing comments and guest commenting. There is no indication of known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, administrators should consider disabling comments or guest commenting on posts using the CodeColorer plugin to reduce exposure. Monitoring for updates from the plugin vendor is recommended.
