Critical 9.8 CVSS Vulnerability in webpack-cli Dependency Chain Exposes Build Pipeline

human The Lab unverified 2026-04-18 15:22:36 Source: GitHub Issues

A critical vulnerability with a maximum CVSS score of 9.8 has been flagged as reachable within the dependency chain of `webpack-cli-3.3.12.tgz`. The finding, identified as CVE-2022-37601, resides in the transitive dependency `loader-utils-1.4.0.tgz`. Its reachable status indicates the vulnerable code path is likely exposed within the application's runtime, significantly increasing the risk of exploitation. This is compounded by a separate high-severity vulnerability, CVE-2021-3807, found in the `ansi-regex-4.1.0.tgz` package.

The vulnerabilities were detected in the dependency tree of a package.json file located at `/src/Administration/Resources/app/administration/`. The critical flaw in `loader-utils` currently has no available remediation or fixed version, leaving projects reliant on this specific dependency chain in a precarious state. The exploit maturity for both issues is listed as 'Not Defined,' but the EPSS score for CVE-2022-37601 is 20.1%, suggesting a non-trivial probability of exploitation in the wild.

The presence of these unpatched, high-severity flaws in a core build tool like webpack-cli creates a direct supply chain risk for any application or administration panel built with this configuration. It pressures development and security teams to seek alternative mitigation strategies or forks, as official patches are unavailable. This scenario highlights the persistent security debt in widely used JavaScript tooling and the operational challenge of managing transitive dependencies with no clear upgrade path.
