Security audit

squarespace

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed Squarespace Commerce integration with OAuth-based access and clear confirmation rules for writes, though users should treat its raw API passthrough as broad account access.

Install only if you intend to let Maton access your Squarespace account for commerce operations. Use the narrowest OAuth scopes available, specify the intended connection when there are multiple accounts, and review every write or delete request carefully because the raw passthrough can call any Squarespace API path allowed by the connected account.

Description-Behavior Mismatch

Medium
Confidence
94% confidence
Finding
The skill claims scope around core commerce entities, but the documented `maton api` passthrough forwards arbitrary native Squarespace paths after `/squarespace/`. That creates a capability/expectation mismatch: an agent or user may assume the skill is limited to listed commerce objects when it can potentially reach broader Squarespace APIs available to the connected account.
