LowOpenSQ-TOOL-EXFIL-SHAPED-PARAM

Free-text parameter commonly used to collect conversation data

A free-text parameter has a name commonly abused to collect conversation, prompt or environment data.

First seen Oct 18, 2026 · Last seen Nov 14, 2026

Suggested fix: Constrain the parameter (enum, maxLength) or rename it to reflect its purpose; never ask the model to fill it with conversation content.

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.
