Published: 18 December 2024
Summary
CVE-2024-56058 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 2.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The vulnerability is a deserialization of untrusted data flaw, tracked as CWE-502, that permits PHP object injection. It affects the VRPConnector WordPress plugin in all versions through 2.0.1. The issue carries a CVSS 3.1 score of 9.8, reflecting network-accessible exploitation without authentication or user interaction and full impact on confidentiality, integrity, and availability.
An unauthenticated attacker can supply a crafted serialized payload over the network to trigger object injection. Successful exploitation allows arbitrary code execution or manipulation of application objects, potentially leading to full site compromise.
The Patchstack advisory at the referenced URL documents the PHP object injection vulnerability in VRPConnector and is the primary source for remediation guidance. The EPSS score has reached a peak of 0.4616 with a current value of 0.4375, indicating sustained exploitation interest following disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
