CVE-2024-5964 is a stored cross-site scripting vulnerability in the Zenon Lite WordPress theme by tislam100, affecting all versions up to and including 1.9. The vulnerability exists due to improper neutralization of input in the 'url' parameter of the theme's Button shortcode, allowing authenticated users with Contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of users who access the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 score of 6.4 (medium severity) with network attack vector, low attack complexity, and no user interaction required. No known exploits in the wild or official patches are documented in the provided data.

An attacker with Contributor-level or higher access can inject persistent malicious scripts via the Button shortcode 'url' parameter. These scripts execute in the browsers of users who view the compromised pages, potentially leading to limited confidentiality and integrity impacts such as theft of user data or session tokens. Availability is not affected. The vulnerability requires authenticated access, limiting the attack surface to users with some level of trust on the site.

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 vulnerable Button shortcode. Monitor for updates from the theme developer or WordPress security advisories for a patch or official mitigation.
