CVE-2020-36327 (GCVE-0-2020-36327)

Vulnerability from cvelistv5 – Published: 2021-04-29 02:28 – Updated: 2024-08-04 17:23

Summary

Bundler 1.16.0 through 2.2.9 and 2.2.11 through 2.2.16 sometimes chooses a dependency source based on the highest gem version number, which means that a rogue gem found at a public source may be chosen, even if the intended choice was a private gem that is a dependency of another private gem that is explicitly depended on by the application. NOTE: it is not correct to use CVE-2021-24105 for every "Dependency Confusion" issue in every product.

Severity

No CVSS data available.
