Name of the Vulnerable Software and Affected Versions Crayon Syntax Highlighter plugin for WordPress versions up to, and including, 2.8.4

Description The issue allows authenticated attackers with contributor-level permissions or above to make web requests to arbitrary locations originating from the web application via the crayon shortcode. This can be used to query and modify information from internal services.

Recommendations For versions up to, and including, 2.8.4, update to a version higher than 2.8.4 to resolve the issue. As a temporary workaround, consider restricting access to the crayon shortcode for users with contributor-level permissions or above until a patch is available.
