The HT Mega Addons for Elementor plugin suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. This flaw exists in the Accordion widget and allows authenticated users with contributor or higher privileges to inject arbitrary JavaScript code via insufficiently sanitized user inputs. When other users access the compromised page, the injected scripts execute, potentially leading to session hijacking or other client-side attacks. The vulnerability affects all versions up to and including 2.4.8. 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, and partial confidentiality and integrity impact without availability impact. No patch or official fix is currently documented.

An authenticated attacker with contributor-level access or higher can inject persistent malicious scripts into pages via the Accordion widget. These scripts execute in the context of users who view the affected pages, potentially compromising user sessions and data confidentiality and integrity. The vulnerability does not impact system availability. No known exploitation in the wild has been reported.

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 avoiding use of the Accordion widget in the HT Mega Addons for Elementor plugin. Monitor vendor channels for updates and apply patches promptly once released.
