Graded by PlugVetRubric v2

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

Rescanned at commit 36ac9d78d66e, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST OBFUSCATION_ENCODED_BLOB

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    skills/release-video/scripts/compose_demo.py, line 106 ff = subprocess.Popen(["ffmpeg", "-v", "error", "-y", "-f", "rawvideo", "-pix_fmt", "rgb24", "-s", f"{W}x{H}", "-r", str(FPS), "-i", "-",

  • NETWORK_NO_FIXED_HOST Low

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

    skills/release-video/scripts/gen_audio.sh, line 11 curl -sf -X POST "https://api.elevenlabs.io/v1/sound-generation" -H "xi-api-key: $ELEVENLABS_API_KEY" \

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    skills/release-video/scripts/gen_audio.sh, line 11 curl -sf -X POST "https://api.elevenlabs.io/v1/sound-generation" -H "xi-api-key: $ELEVENLABS_API_KEY" \

  • OBFUSCATION_ENCODED_BLOB Low

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

    skills/museum-art/references/smk.md, line 103 "image_native": "https://api.smk.dk/api/v1/download/W3siaW1nX3VybCI6Imh0dHBzOi8vaWlwLnNtay5kay9paWlmL2pwMi9xejIwc3g3NzFfa2tzNTI2MS50aWYuanAyL2Z1bGwvZnVsbC8wL25hdGl2ZS5qcGciLCJwdWJs

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.
