Deeper analysis

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.
