Rescanned at commit b9f1ee8c4f46, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST OBFUSCATION_ENCODED_BLOB SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/agent.ts, line 465 const state = await (program.account as any).cloakedAgentState.fetch(agentStatePda);

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    src/agent.ts, line 465 const state = await (program.account as any).cloakedAgentState.fetch(agentStatePda);

  • OBFUSCATION_ENCODED_BLOB Low

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

    src/zk/ownership_proof.json, line 1 {"noir_version":"1.0.0-beta.18+99bb8b5cf33d7669adbdef096b12d80f30b4c0c9","hash":"215865484024365799","abi":{"parameters":[{"name":"agent_secret","type":{"kind":"field"},"visibility

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    src/mcp/index.ts, line 399 const agentKey = process.env.CLOAKED_AGENT_KEY;

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.
