Description

The Crayon Syntax Highlighter plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 2.6.10 via the 'data-url' parameter. This allows unauthenticated attackers to read the contents of arbitrary files on the server, potentially outside the web root, which can contain sensitive information.
