In plain English
A high-severity unsafe deserialization in Link Whisper Free from linkwhspr. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.8% (higher than 57% of all known vulnerabilities).
Official description
The Link Whisper Free plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 0.7.1 via deserialization of untrusted input of the 'mfn-page-items' post meta value. This makes it possible for authenticated attackers, with contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable plugin. 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.
