Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit cf7560c4f833, unchanged since the check below.

INSTALL_REMOTE_SCRIPT OBFUSCATION_ENCODED_BLOB OBFUSCATION_MINIFIED_PAYLOAD

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).

    Dockerfile, line 8 && curl -fsSL https://deb.nodesource.com/setup_20.x | bash - \

  • OBFUSCATION_ENCODED_BLOB Medium

    Contains a long base64 shaped string in a file that should be readable.

    api/xhs_api.py, line 148 headers['x-s-common']='2UQAPsHCPUIjqArjwjHjNsQhPsHCH0rjNsQhPaHCH0c1PahIHjIj2eHjwjQ+GnPW/MPjNsQhPUHCHdYiqUMIGUM78nHjNsQh+sHCH0c1+0H1PUHVHdWMH0ijP/DAP9L9P/DhPerUJoL72nIM+9Qf8fpC2fHA8

  • OBFUSCATION_MINIFIED_PAYLOAD Medium

    Contains a very long line with almost no spaces in a script or style file.

    api/xhs_api.py, line 148 headers['x-s-common']='2UQAPsHCPUIjqArjwjHjNsQhPsHCH0rjNsQhPaHCH0c1PahIHjIj2eHjwjQ+GnPW/MPjNsQhPUHCHdYiqUMIGUM78nHjNsQh+sHCH0c1+0H1PUHVHdWMH0ijP/DAP9L9P/DhPerUJoL72nIM+9Qf8fpC2fHA8

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.
