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

Rescanned at commit 98578ad59da2, unchanged since the check below.

OBFUSCATION_ENCODED_BLOB OBFUSCATION_MINIFIED_PAYLOAD

Why this grade

  • OBFUSCATION_ENCODED_BLOB Medium

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

    src/fonts.js, line 1 // Self-hosted fonts (Google Fonts, OFL): Instrument Serif italic, IBM Plex Sans 400/500, IBM Plex Mono 400, latin.

  • OBFUSCATION_MINIFIED_PAYLOAD Medium

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

    src/fonts.js, line 1 // Self-hosted fonts (Google Fonts, OFL): Instrument Serif italic, IBM Plex Sans 400/500, IBM Plex Mono 400, latin.

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.
