Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Flaw remediation directly addresses CVE-2025-50004 by patching the JupiterX Core plugin to eliminate the unsafe deserialization of untrusted data.
Information input validation prevents deserialization of untrusted data in the WordPress plugin by ensuring only valid inputs are processed.
Vulnerability monitoring and scanning identifies the presence of CVE-2025-50004 in deployed JupiterX Core plugin versions for timely remediation.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Deserialization/object injection in public-facing WordPress plugin directly enables remote exploitation (T1190) by low-privileged authenticated users, resulting in full confidentiality/integrity/availability impact equivalent to privilege escalation (T1068).

Deeper analysisAI
CVE-2025-50004 is a Deserialization of Untrusted Data vulnerability (CWE-502) in the artbees JupiterX Core (jupiterx-core) WordPress plugin, enabling Object Injection. The issue affects all versions of JupiterX Core from n/a through 4.10.1. Published on 2026-01-22, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact on confidentiality, integrity, and availability.
An attacker with low privileges, such as an authenticated WordPress user, can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation allows object injection through untrusted deserialization, potentially leading to high-impact outcomes including unauthorized data access, modification, or disruption of system availability.
