The Prime Slider – Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. This flaw allows authenticated users with contributor-level privileges or above to inject malicious scripts via URLs in link fields, image URLs, and HTML tags within widgets. These scripts execute in the context of users viewing the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to and including 3.14.0. The CVSS 3.1 vector indicates network attack vector, low attack complexity, privileges required at the contributor level, no user interaction needed, and impacts confidentiality and integrity with no availability impact.

An attacker with contributor-level access or higher can inject persistent malicious scripts into pages using the vulnerable plugin. These scripts execute in the browsers of users who visit the affected pages, potentially compromising user data confidentiality and integrity. The impact is limited to confidentiality and integrity with no direct availability impact. There are no reports of active exploitation 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, restrict contributor-level access to trusted users only and consider disabling or removing the vulnerable plugin to prevent exploitation. Monitor for updates from the vendor or WordPress plugin repository regarding patches or mitigations.
