OBFUSCATION_MINIFIED_PAYLOAD

Why this grade

  • OBFUSCATION_MINIFIED_PAYLOAD Medium

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

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.
