Deeper analysis
The Cooked Pro WordPress plugin before version 1.7.5.7 contains a PHP Object injection vulnerability. The plugin fails to properly validate or sanitize the recipe_args parameter prior to unserializing it when handling the cooked_loadmore action, which can be reached without authentication.
An unauthenticated attacker can supply a crafted serialized object via this parameter over the network. Successful exploitation yields arbitrary PHP object instantiation, which under the right gadget chains can lead to remote code execution, data disclosure, or other impacts consistent with the CVSS 9.8 rating.
The vulnerability is addressed by updating to Cooked Pro 1.7.5.7 or later, as indicated by the affected-version range in public advisories.
EPSS for this CVE rose from a low baseline to a peak of 0.3333 on 2025-12-11 before receding to the current value of 0.0430, indicating a period of increased exploitation interest after disclosure.
