CVE-2020-36327

CVSS v2.0

9.3

High

VectorAV:N/AC:M/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions: Bundler versions 1.16.0 through 2.2.9 Bundler versions 2.2.11 through 2.2.16
Description: The issue sometimes chooses a dependency source based on the highest gem version number. This means 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 explicitly depended on by the application.
Recommendations: For Bundler versions 1.16.0 through 2.2.9, consider updating to a version outside of this range to mitigate the risk. For Bundler versions 2.2.11 through 2.2.16, consider updating to a version outside of this range to mitigate the risk. As a temporary workaround, consider restricting the use of public gem sources to minimize the risk of exploitation.
