CVE-2024-9848 is a stored cross-site scripting vulnerability in the Product Customizer Light WordPress plugin by k2servicecom. It affects all versions up to and including 1.0.0. The issue stems from improper neutralization of input during web page generation, specifically insufficient sanitization and output escaping of SVG file uploads. Authenticated users with Author-level privileges or higher can exploit this to inject arbitrary web scripts that execute when the SVG file is viewed. The vulnerability has a CVSS 3.1 base score of 6.4 (medium severity), with network attack vector, low attack complexity, and no user interaction required.

Successful exploitation allows an authenticated user with Author-level access or higher to inject and execute arbitrary JavaScript in the context of the affected WordPress site. This can lead to limited confidentiality and integrity impacts, such as session hijacking or content manipulation. There is no impact on availability reported. The vulnerability requires authenticated access and is not known to be exploited in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Author-level access to trusted users only and consider disabling SVG file uploads if possible. Monitor for updates from the vendor regarding patches or official fixes.
