Grade D
Two or more Medium findings, or a High finding. Only try it in a sandbox.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
INSTALL_REMOTE_SCRIPT PERMISSION_SHELL_UNDECLARED NETWORK_HOST_FROM_INPUT
Why this grade
- INSTALL_REMOTE_SCRIPT High
Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).
AGENTS.md, line 139
- Unix installer: `curl -fsSL https://github.com/aryaminus/controlkeel/releases/latest/download/install.sh | sh` - PERMISSION_SHELL_UNDECLARED Medium
Runs shell commands that the manifest or description does not mention.
scripts/bump_version.py, line 96
result = subprocess.run( - NETWORK_HOST_FROM_INPUT Medium
A file takes a URL or endpoint as input and has no fixed host list.
lib/controlkeel/accounts/oauth_providers.ex, line 9
* **GitHub** - OAuth2 authorize + token + `/user` fetch (email + name).
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.

Install and update

install fetches a script from the network. The docs document an installer that pipes a download into a shell. README documents an installer that pipes a download into a shell.
