CVE-2024-4780 is a stored cross-site scripting vulnerability in the Image Hover Effects – Elementor Addon plugin for WordPress, affecting all versions up to and including 1.4.3. The vulnerability exists due to improper neutralization of input in the 'eihe_link' parameter, allowing authenticated users with Contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of users visiting the injected pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 score of 6.4 reflects a medium severity with network attack vector, low attack complexity, and privileges required at the contributor level.

An attacker with Contributor-level access or higher can exploit this vulnerability to inject persistent malicious scripts into pages using the vulnerable plugin. These scripts execute in the browsers of users who view the compromised pages, potentially leading to theft of user credentials, session tokens, or other malicious actions within the context of the affected site. There is no indication of impact on availability. The vulnerability requires authentication and is limited to sites using the affected plugin versions.

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 removing the Image Hover Effects – Elementor Addon plugin if feasible. Monitor for plugin updates from the vendor that address this vulnerability.
