This vulnerability involves CWE-502: Deserialization of Untrusted Data in the MetaSlider Responsive Slider plugin. It allows an attacker with high privileges to inject malicious objects via deserialization, potentially leading to full compromise of the affected system. The vulnerability affects all versions up to 3.106.0. The CVSS 3.1 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 official remediation level has been published by the vendor as of the publication date.

Successful exploitation can lead to complete compromise of the affected system, including unauthorized disclosure, modification, or destruction of data, and disruption of service. The attacker must have high privileges to exploit this vulnerability, which limits the attack surface but does not eliminate the risk. No known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the plugin to trusted users only and monitor for suspicious activity related to deserialization processes. Avoid using untrusted data inputs with the plugin. Follow vendor channels for updates on patches or mitigations.
