Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Flaw remediation directly addresses CVE-2025-50004 by patching the JupiterX Core plugin to eliminate the unsafe deserialization of untrusted data.

prevent

Information input validation prevents deserialization of untrusted data in the WordPress plugin by ensuring only valid inputs are processed.

detect

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

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1068 Exploitation for Privilege Escalation Privilege Escalation
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
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).

NVD Description

Deserialization of Untrusted Data vulnerability in artbees JupiterX Core jupiterx-core allows Object Injection.This issue affects JupiterX Core: from n/a through <= 4.10.1.

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.

The Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/jupiterx-core/vulnerability/wordpress-jupiterx-core-plugin-4-10-1-php-object-injection-vulnerability?_s_id=cve details the PHP object injection vulnerability in JupiterX Core version 4.10.1 and provides information on mitigation, including recommendations for updating the plugin.
