CVE-2024-0838 is a stored cross-site scripting vulnerability in the Happy Addons for Elementor WordPress plugin, affecting all versions up to 3.10.1. The flaw exists in the Age Gate component where the side image URL parameter is not properly sanitized or escaped, allowing authenticated users with contributor-level access or higher to inject arbitrary web scripts. These scripts execute in the context of users who visit the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability is classified under CWE-79 and has a CVSS 3.1 base score of 6.4 (medium severity). No patch or official fix information is currently available.

An attacker with contributor or higher privileges can exploit this vulnerability to inject malicious scripts that execute in the browsers of users who access the compromised pages. This can lead to limited confidentiality and integrity impacts such as theft of user credentials or session tokens. There is no indication of availability impact. The vulnerability requires authenticated access and low attack complexity.

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 limiting use of the Age Gate feature.
