CVE-2024-1377 is a stored cross-site scripting vulnerability (CWE-79) in the Happy Addons for Elementor plugin for WordPress. The issue arises from insufficient input sanitization and output escaping of the 'author_meta_tag' attribute in the Author Meta widget. Authenticated attackers with contributor-level privileges or higher can exploit this flaw to inject arbitrary web scripts into pages, which execute in the context of users viewing those pages. This vulnerability affects all versions up to and including 3.10.3. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability.

Successful exploitation allows an authenticated user with contributor-level access or higher to inject malicious scripts that execute in the browsers of users who visit the compromised pages. This can lead to unauthorized actions performed on behalf of users, theft of sensitive information, or other client-side impacts. The vulnerability does not affect availability. There are no known exploits in the wild as of the published date.

No official patch or fix is currently referenced in the provided data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or removing the affected Author Meta widget if feasible. Monitor official vendor channels for updates and apply patches promptly once released.
