CVE-2024-47068
Description
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.
Statement
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.
Mitigation
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.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
