CVE-2024-4392 is a stored cross-site scripting vulnerability in the Jetpack – WP Security, Backup, Speed, & Growth WordPress plugin. It occurs due to improper neutralization of input during web page generation, specifically in the wpvideo shortcode, where user-supplied attributes are not properly sanitized or escaped. This allows authenticated attackers with contributor-level privileges or higher to inject malicious scripts that execute in the context of users viewing the compromised pages. The vulnerability affects all versions up to 13.3.1. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, privileges required at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability. No patch or official vendor advisory is currently available in the provided data.

Successful exploitation allows an authenticated contributor or higher to inject and store malicious scripts within pages using the wpvideo shortcode. These scripts execute in the browsers of users who view the affected pages, potentially leading to unauthorized actions or data disclosure within the context of the affected site. The impact affects confidentiality and integrity but does not affect availability. There are no known exploits in the wild as of the published date.

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 limiting use of the wpvideo shortcode to reduce exposure. Monitor vendor channels for updates and apply any official patches promptly once available.
