The Happy Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) identified as CVE-2024-5088. This vulnerability is due to improper neutralization of input during web page generation, specifically involving the '_id' parameter. Authenticated attackers with Contributor-level privileges or higher can exploit this flaw to inject malicious scripts that persist in pages and execute when accessed by other users. The vulnerability affects all versions up to 3.10.8. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required, no user interaction, and impact on confidentiality and integrity but not availability. No patch or vendor advisory is currently available, and no known exploits have been reported.

Successful exploitation allows an authenticated user with Contributor-level access or higher to inject persistent malicious scripts into pages generated by the plugin. This can lead to unauthorized actions or data disclosure when other users view the infected pages. The impact affects confidentiality and integrity but 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 released, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the affected plugin. Monitor for updates from the vendor regarding patches or mitigations.
