Addfunc Head Footer Code
Monthly
Stored cross-site scripting (XSS) in AddFunc Head & Footer Code plugin for WordPress versions up to 2.3 allows authenticated attackers with Contributor-level access to inject arbitrary JavaScript via custom post meta fields that execute when administrators preview or view posts. The vulnerability exists because the plugin outputs user-supplied code from `aFhfc_head_code`, `aFhfc_body_code`, and `aFhfc_footer_code` meta values without sanitization or escaping, and fails to restrict meta key access via WordPress `register_meta()` authentication callbacks despite restricting its own admin interface. No public exploit code or active exploitation has been confirmed at time of analysis.
