CVE-2024-11451 is a stored cross-site scripting vulnerability in the harshitpeer Zooom WordPress plugin, affecting all versions up to and including 1.1.0. The issue stems from improper neutralization of input during web page generation, specifically insufficient input sanitization and output escaping on user-supplied attributes within the 'zooom' shortcode. Authenticated users with contributor-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of any user viewing the injected page. This vulnerability can lead to limited confidentiality and integrity impacts but does not affect availability.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable shortcode. These scripts execute in the browsers of users who visit the compromised pages, potentially leading to theft of user credentials, session tokens, or other sensitive information accessible through the browser context. The impact is limited to confidentiality and integrity, with no direct impact on system availability. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the Zooom plugin if possible. Monitor for plugin updates from the vendor that address this vulnerability and apply them promptly once available.
