Summary

CVE-2025-46183 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability. Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 37.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2025-46183 is an insecure deserialization vulnerability in the Utils.deserialize function of pgCodeKeeper version 10.12.0. The function processes serialized data from untrusted sources, allowing a specially crafted .ser file to trigger unintended code execution or other malicious behavior on the target system. It carries a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N) and maps to CWE-502: Deserialization of Untrusted Data.

Remote attackers require no privileges or user interaction to exploit this vulnerability over the network with low complexity. By supplying a malicious .ser file to the deserialization process, they can achieve arbitrary code execution or similar malicious effects, leading to high integrity impact such as data tampering and low confidentiality impact.
