automattic/zoninator is vulnerable to Insecure Deserialization
79
High Risk
This Affects:
automattic/zoninatorTL;DR
Zone details were stored by serializing an array into the term description and read back using maybe_unserialize. That makes the description field a high-traffic PHP deserialization sink. The fix replaces maybe_unserialize with an explicit is_serialized check and performs unserialize with allowed_classes=false, rejecting non-array results so attacker-controlled payloads cannot trigger PHP object instantiation/POP-gadget execution.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
