The Element Pack Elementor Addons plugin for WordPress suffers from a stored cross-site scripting vulnerability due to improper neutralization of input during web page generation. Specifically, the 'social-link-title' parameter is not properly sanitized or escaped, allowing authenticated users with Contributor-level privileges or higher to inject arbitrary scripts. These scripts execute in the context of users who visit the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to and including 5.6.5. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and partial confidentiality and integrity impact.

An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable parameter. These scripts execute in the browsers of users who view the infected pages, potentially compromising user sessions or performing unauthorized actions within the context of the affected site. The impact is limited to confidentiality and integrity loss, with no availability impact reported. There are no known active exploits in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider removing or disabling the vulnerable plugin if possible. Monitor official bdthemes communications for updates regarding patches or mitigations.
