The Slider Revolution plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the plugin fails to adequately sanitize and escape the 'wrapperid' and 'zindex' attributes supplied via Elementor, allowing authenticated users with contributor or higher privileges to inject arbitrary JavaScript. This malicious code executes in the context of any user viewing the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to 6.7.10 and has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N).

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages using the vulnerable Slider Revolution plugin. These scripts execute in the browsers of users who visit the infected pages, potentially leading to data theft, session hijacking, or other client-side attacks. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no reports of active exploitation in the wild at this time.

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 limiting use of the affected Elementor attributes in Slider Revolution. Monitor vendor channels for updates and apply patches promptly once released.
