The vulnerability CVE-2025-58839 affects the eDS Responsive Menu plugin by aThemeArt Translations. It arises from unsafe deserialization of untrusted data, enabling an attacker with high privileges to perform object injection. This can result in full compromise of the system's confidentiality, integrity, and availability. The affected versions include all versions up to 1.2. The CVSS v3.1 base score is 7.2, reflecting network attack vector, low attack complexity, high privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No patch or vendor advisory is currently available.

Successful exploitation of this vulnerability allows an attacker with high privileges to inject malicious objects via deserialization, potentially leading to full system compromise including data theft, modification, or denial of service. The impact is rated high due to the complete loss of confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the affected plugin and limit privileges to trusted users only to reduce exploitation risk.
