OVERVIEW

        A number of security vulnerabilities have been identified in WordPress
        prior to version 3.8.2. [1]


IMPACT

        The vendor has provided the following details regarding these 
        vulnerabilities:
        
        "This releases fixes a weakness that could let an attacker force their 
        way into your site by forging authentication cookies. This was 
        discovered and fixed by Jon Cave of the WordPress security team.
        
        It also contains a fix to prevent a user with the Contributor role 
        from improperly publishing posts. Reported by edik.
        
        This release also fixes nine bugs and contains three other security 
        hardening changes:
        
        - Pass along additional information when processing pingbacks to help 
        hosts identify potentially abusive requests.
        - Fix a low-impact SQL injection by trusted users. Reported by Tom 
        Adams of dxw.
        - Prevent possible cross-domain scripting through Plupload, the 
        third-party library WordPress uses for uploading files. Reported by 
        Szymon Gruszecki." [1, 2]


MITIGATION

        The vendor recommends that administrators update to the latest
        version of WordPress to correct these issues. [1]
