CVE-2024-2803 is a stored cross-site scripting vulnerability (CWE-79) in the ElementsKit Elementor Addons plugin for WordPress, specifically affecting the countdown widget. The flaw is due to improper neutralization of input during web page generation, allowing authenticated users with contributor or higher privileges to inject malicious scripts via user-supplied attributes. These scripts execute in the context of users who access the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to 3.0.6. 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 limited privileges required.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the countdown widget. These scripts execute in the browsers of users who visit the compromised pages, potentially leading to limited confidentiality and integrity impacts such as theft of session tokens or manipulation of page content. There is no impact on availability. No known active exploitation 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 countdown widget in the ElementsKit Elementor Addons plugin. Monitor for updates from the vendor or plugin maintainers regarding patches or official mitigations.
