INSTALL_REMOTE_SCRIPT NETWORK_HOST_FROM_INPUT OBFUSCATION_ENCODED_BLOB
Why this grade
- INSTALL_REMOTE_SCRIPT Medium
Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).
README.md, line 96
curl -fsSL https://taprun.dev/install.sh | sh # permanent binary - NETWORK_HOST_FROM_INPUT Medium
A file takes a URL or endpoint as input and has no fixed host list.
docs/install.sh, line 93
curl -fsSL "${BASE_URL}/${BINARY}" -o "${TMP}/tap" - OBFUSCATION_ENCODED_BLOB Medium
Contains a long base64 shaped string in a file that should be readable.

/**
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.
