A code injection vulnerability was identified in GitHub Enterprise Server that allowed setting arbitrary environment variables from a single environment variable value in GitHub Actions when using a Windows based runner. To exploit this vulnerability, an attacker would need existing permission to control the value of environment variables for use with GitHub Actions. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.8.0 and was fixed in versions 3.4.15, 3.5.12, 3.6.8, 3.7.5. This vulnerability was reported via the GitHub Bug Bounty program.

Ubuntu Security Notice 5896-1 - It was discovered that Rack was not properly parsing data when processing multipart POST requests. If a user or automated system were tricked into sending a specially crafted multipart POST request to an application using Rack, a remote attacker could possibly use this issue to cause a denial of service. It was discovered that Rack was not properly escaping untrusted data when performing logging operations, which could cause shell escaped sequences to be written to a terminal. If a user or automated system were tricked into sending a specially crafted request to an application using Rack, a remote attacker could possibly use this issue to execute arbitrary code in the machine running the application.
