CVE-2024-47068

A flaw was found in the Rollup module bundler for JavaScript. Certain versions are susceptible to a DOM Clobbering vulnerability when bundling scripts with properties from import.meta such as import.meta.url in the cjs/umd/iife format. The DOM Clobbering gadget can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements are present, for example, an img tag with an unsanitized name attribute.

This vulnerability is classified as moderate severity rather than important because it requires a specific and relatively uncommon attack vector to exploit—namely, attacker-controlled scriptless HTML elements, such as an unsanitized name attribute in an img tag, which are typically less prevalent in well-maintained web applications. Additionally, the impact is limited to scenarios where import.meta is improperly handled in specific module formats (cjs, umd, iife), and the vulnerability can only lead to cross-site scripting (XSS) under specific conditions.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
