Vulnerability AssessmentAI

Risk Assessment	Real-world risk is elevated despite missing CVSS and EPSS scores. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	An attacker crafts a malicious serialized PHP object and injects it into a request parameter, form field, or database value processed by the Halstein theme. When the theme's code deserializes this object using unserialize() without validation, the attacker's payload instantiates a gadget chain—a sequence of existing PHP classes with magic methods—that ultimately executes arbitrary shell commands, reads sensitive files, or modifies website content with administrator privileges. …
Remediation	Immediately upgrade Mikado-Themes Halstein to version 1.8 or later from the official WordPress theme repository or vendor website. … Detailed patch versions, workarounds, and compensating controls in full report.
