Summary
CVE-2024-56058 is a critical-severity Deserialization of Untrusted Data (CWE-502) vulnerability. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked in the top 22% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Integrity verification tools can detect malformed or tampered serialized data after the fact.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.
Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.
Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
