Severity: High1 finding

Severity: HighStatus: OpenSQ-TOOL-SENSITIVE-PATH-REFERENCE

References credential or key locations

Model-facing text references credential, key or configuration file locations unrelated to the tool's stated purpose.

First seen · Last seen

Suggested fix: Remove references to credential files, key stores and client configuration files.

Severity: Medium1 finding

Severity: MediumStatus: OpenSQ-TOOL-INJECTION-INSTRUCTIONS

What this scan does not cover

  • Squatch never calls a server's tools, so it cannot see what they actually do at run time.
  • It scans without credentials: tools behind authentication may not be visible.
  • It does not review source code, dependencies or the publisher's infrastructure.
  • A server can change behavior between scans; monitoring compares each scan with the last.
  • Classifications come from tool names, descriptions and schemas, which the publisher controls.
