The Elementor Addon Elements plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. This allows authenticated users with contributor-level privileges or above to inject arbitrary scripts via multiple widgets because the plugin fails to properly sanitize and escape user-supplied attributes. The vulnerability affects all versions up to and including 1.13.6. Exploitation results in script execution in the context of users who visit the compromised pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, and privileges required at the contributor level.

Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages, which execute in the browsers of users who view those pages. This can lead to information disclosure, session hijacking, or other client-side attacks. The impact is limited by the requirement for contributor-level access and the absence of known active exploitation. There is no indication of impact on availability or server integrity.

No official patch or remediation guidance is currently provided by the vendor. 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 limiting the use of affected widgets. Monitor for updates from the vendor or security advisories for a released patch.
