CVE-2022-46179

9.2 CRITICAL 0.3% exploit odds Fix listed Auth & access

What it is

LiuOS is a small Python project meant to imitate the functions of a regular operating system. Version 0.1.0 and prior of LiuOS allow an attacker to set the GITHUB_ACTIONS environment variable to anything other than null or true and skip authentication checks. This issue is patched in the latest commit (c658b4f3e57258acf5f6207a90c2f2169698ae22) by requiring the var to be set to true, causing a test script to run instead of being able to login. A potential workaround is to check for the GITHUB_ACTIONS environment variable and set it to "" (no quotes) to null the variable and force credential checks.
