Technical details
The vulnerability exists in the set_meta() function in includes/utils.php, which unserializes untrusted post metadata during content distribution. An attacker with Contributor-level privileges can craft a malicious serialized payload and store it as post meta; when distributed to another site, the double-unserialization process allows instantiation of arbitrary PHP objects whose impact depends on available gadget chains in loaded classes.
