Rescanned at commit 661c5823287f, unchanged since the check below.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST OBFUSCATION_ENCODED_BLOB OBFUSCATION_MINIFIED_PAYLOAD

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 1 loggus

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    pywss/utils.py, line 35 def fetch(self, *args):

  • OBFUSCATION_ENCODED_BLOB Low

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

    demo/apache/luckysheet/static/js/luckysheet.umd.js, line 1 !function(e,t){"object"==typeof exports&&"undefined"!=typeof module?module.exports=t():"function"==typeof define&&define.amd?define(t):(e="undefined"!=typeof globalThis?globalThis:

  • OBFUSCATION_MINIFIED_PAYLOAD Low

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

    demo/apache/luckysheet/static/js/luckysheet.umd.js, line 1 !function(e,t){"object"==typeof exports&&"undefined"!=typeof module?module.exports=t():"function"==typeof define&&define.amd?define(t):(e="undefined"!=typeof globalThis?globalThis:

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.

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.
