CodeColorer WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the CodeColorer plugin for WordPress, affecting versions through 0.10.1. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts into pages. These scripts execute when users access the affected pages. Exploitation requires comments to be enabled on the target post and guest comments to be allowed.

Impact

Successful exploitation allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Remediation

Users can update to CodeColorer version 0.10.2 or a newer patched version to address this vulnerability.
