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

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    actor/src/server.ts, line 224 const response = await fetch(`https://api.apify.com/.well-known/oauth-authorization-server`);

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    actor/src/server.ts, line 224 const response = await fetch(`https://api.apify.com/.well-known/oauth-authorization-server`);

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    server.mcpb, line 1 PK1

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.
