Description
The DoFollow Case by Case plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 3.6.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Comment moderation delays but does not prevent exploitation — once an administrator approves the visually innocuous comment, the stored payload executes in the browser of every subsequent visitor to the affected post.
