Building With Sarvam

Building With Sarvam, a skill listed in the PlugVet directory.

Compatibility: Not stated.

Grade D

Two or more Medium findings, or a High finding. Only try it in a sandbox.

Graded by PlugVetRubric v2

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

Rescanned at commit 6e10d3d9a6f3, unchanged since the check below.

PERMISSION_SHELL_UNDECLARED OBFUSCATION_ENCODED_BLOB

Why this grade

  • PERMISSION_SHELL_UNDECLARED Medium

    Runs shell commands that the manifest or description does not mention.

    Labs/09_Framework_Interop_LangChain_LangGraph_CrewAI_n8n.ipynb, line 2016 " p = subprocess.Popen(\n",

  • OBFUSCATION_ENCODED_BLOB Medium

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

    Labs/01_The_Sampler_Every_API_in_One_Script.ipynb, line 1 {

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Concern

    requests shell access. No manifest field names shell or command execution.

    PERMISSION_SHELL_UNDECLARED

  • Install and update

    Concern

    dependencies are not pinned.

    INSTALL_UNPINNED

    requirements.txt, line 9

    sarvamai>=0.1.30 # 0.1.30 added speech_to_text_realtime_streaming

  • Network

    Concern

    can reach www.apache.org. The description does not name that host. can reach a host that is not written as a fixed address.
