CVE-2024-12312
Published: 12 December 2024
Summary
CVE-2024-12312 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Wordpress (inferred from references). Its CVSS base score is 8.1 (High).
Operationally, ranked in the top 7.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The Print Science Designer plugin for WordPress is vulnerable to PHP Object Injection (CWE-502) in all versions through 1.3.152. The flaw stems from unsafe deserialization of untrusted data supplied via the designer-saved-projects cookie, allowing an attacker to inject arbitrary PHP objects into the application. No POP chain is present in the plugin itself, but the presence of a suitable chain from another installed plugin or theme could enable further abuse.
Unauthenticated attackers can exploit the issue remotely over the network, though the attack requires high complexity. Successful exploitation could permit deletion of arbitrary files, disclosure of sensitive data, or remote code execution when a usable POP chain is available on the target system.
The referenced Wordfence advisory and WordPress plugin repository entries indicate that the issue is resolved in version 1.3.153, which updates the handling of the affected cookie in saved-projects.php. Administrators should update the plugin to this or a later release to eliminate the deserialization vector.
The associated EPSS score remains flat at 0.0785 with no material increase observed after disclosure.

PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

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.
