Name of the Vulnerable Software and Affected Versions ConvertPlug plugin for WordPress versions up to, and including, 3.5.25

Description The issue concerns PHP Object Injection via deserialization of untrusted input from the settings encoded attribute of the "smile info bar" shortcode. This allows authenticated attackers with contributor-level access and above to inject a PHP Object. If a POP chain is present via an additional plugin or theme, it could enable the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

Recommendations For versions up to, and including, 3.5.25, update to a version that contains a fix for this issue to prevent PHP Object Injection. As a temporary workaround, consider restricting access to the "smile info bar" shortcode and the settings encoded attribute to minimize the risk of exploitation.
