Name of the Vulnerable Software and Affected Versions Link Whisper Free plugin for WordPress versions up to, and including, 0.7.1

Description The issue allows authenticated attackers with contributor-level access and above to inject a PHP Object via deserialization of untrusted input of the mfn-page-items post meta value. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

Recommendations For versions up to, and including, 0.7.1, update to a version that fixes the PHP Object Injection issue to prevent exploitation. As a temporary workaround, consider restricting access to the mfn-page-items post meta value to minimize the risk of exploitation.
