An attacker with high privileges and requiring user interaction can inject malicious scripts that execute in the context of other users. The vulnerability has a CVSS 3.1 base score of 5.9, reflecting network attack vector, low attack complexity, high privileges required, user interaction required, and impacts on confidentiality, integrity, and availability at a low to low level. No patch or official remediation level has been published by the vendor as of now.

Successful exploitation could allow an attacker with high privileges to inject malicious scripts that execute in other users' browsers, potentially leading to limited confidentiality, integrity, and availability impacts. The attack requires user interaction and high privileges, which limits the scope and ease of exploitation. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to high-privilege accounts and limit user interactions with untrusted content within the affected plugin. Monitor vendor channels for updates and apply patches promptly once available.
