The Prime Slider – Addons for Elementor plugin suffers from a stored cross-site scripting vulnerability due to improper neutralization of input in the 'settings["title_tags"]' attribute of the Mercury widget. This allows authenticated users with contributor or higher privileges to inject arbitrary JavaScript code into pages, which executes in the context of users viewing those pages. The vulnerability affects all plugin versions up to 3.13.2. The CVSS 3.1 base score is 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, required privileges at contributor level, no user interaction, scope changed, and low impact on confidentiality and integrity, with no impact on availability. No patch or official fix has been documented in the provided data.

An attacker with contributor-level access or higher can exploit this vulnerability to inject persistent malicious scripts into pages generated by the plugin. These scripts execute in the browsers of users who view the compromised pages, potentially leading to theft of user credentials, session tokens, or other sensitive information accessible via the browser context. The vulnerability does not impact system availability. There are no known exploits in the wild at this time.

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