Halstein
Monthly
This is a deserialization of untrusted data vulnerability in the Mikado-Themes Halstein WordPress theme (versions prior to 1.8) that allows arbitrary object injection via CWE-502. An attacker can exploit this flaw to instantiate arbitrary PHP objects, potentially leading to remote code execution or information disclosure depending on available gadget chains. The vulnerability was reported by Patchstack and affects all versions of Halstein below 1.8; no CVSS score, EPSS data, or KEV status is currently published, limiting immediate risk quantification but indicating this is a serious deserialization flaw that should be patched urgently.
