Grade D
Two or more Medium findings, or a High finding. Only try it in a sandbox.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit dceb4647dc26, unchanged since the check below.
NETWORK_HOST_FROM_INPUT OBFUSCATION_MINIFIED_PAYLOAD
Why this grade
- NETWORK_HOST_FROM_INPUT Medium
A file takes a URL or endpoint as input and has no fixed host list.
aggrete/approvals.py, line 163
httpx.post(url, json={"text": text, "aggrete": req}, timeout=5.0) - OBFUSCATION_MINIFIED_PAYLOAD Medium
Contains a very long line with almost no spaces in a script or style file.
aggrete/extmcp/ext_mcp_pb2.py, line 28
DESCRIPTOR = _descriptor_pool.Default().AddSerializedFile(b'\n\rext_mcp.proto\x12\x18\x61gentgateway.dev.ext_mcp\x1a\x1cgoogle/protobuf/struct.proto\"\xc6\x01\n\nMcpRequest\x12\x15
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.
If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.
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.
