Date: 2022-06
Affected: rubygems/octokit
Attack vector: other
Category: vulnerability-disclosure
Severity: Low
CVE: CVE-2022-31072
CWE: CWE-276
CVSS: 2.5 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N)

### Impact Versions [4.23.0](https://rubygems.org/gems/octokit/versions/4.23.0) and [4.24.0](https://rubygems.org/gems/octokit/versions/4.24.0) of the octokit gem were published containing world-writeable files. Specifically, the gem was packed with files having their permissions set to `-rw-rw-rw-` (i.e. 0666) instead of `rw-r--r--` (i.e. 0644). This means everyone who is not the owner (Group and Public) with access to the instance where this release had been installed could modify the world-writable files from this gem. Malicious code already present and running on your machine, separate from this package, could modify the gem’s files and change its behavior during runtime. ### Patches * [octokit 4.25.0](https://rubygems.org/gems/octokit/versions/4.25.0) ### Workarounds Users can use the previous version of the gem [v4.22.0](https://rubygems.org/gems/octokit/versions/4.22.0). Alternatively, users can modify the file permissions manually until they are able to upgrade to the latest version.
