The HT Mega Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input in the 'border_type' attribute of the Post Carousel widget. This flaw allows authenticated users with contributor or higher privileges to inject arbitrary JavaScript code that executes in the context of other users viewing the compromised pages. The vulnerability affects all versions up to and including 2.4.4. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability. No patch or official remediation guidance is currently documented in the provided data.

An attacker with contributor-level access or higher can exploit this vulnerability to inject persistent malicious scripts into web pages generated by the vulnerable plugin. This can lead to unauthorized actions performed in the context of other users, potentially compromising user data confidentiality and integrity. The vulnerability does not affect 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, restrict contributor-level access to trusted users only and consider disabling or removing the vulnerable Post Carousel widget if feasible. Monitor official channels for updates from the plugin vendor regarding patches or mitigations.
