Api Sports

Security checks across malware telemetry and agentic risk

Overview

This is a disclosed API Sports integration that uses Membrane for authentication and API access, with no evidence of hidden or destructive behavior.

Install only if you trust Membrane and the @membranehq CLI package. Complete authentication yourself, verify the connection is for API Sports, and treat raw proxy requests carefully, especially any non-GET method, because they use your delegated API credentials.

Description-Behavior Mismatch

Medium
Confidence
91% confidence
Finding
The skill is scoped as an API Sports integration, but these instructions allow the agent to create a new Membrane app/connector automatically when no known app matches the supplied URL. That expands behavior from a bounded sports-data integration into generic connector creation against arbitrary domains, increasing the risk of unintended external access and scope creep beyond what the manifest communicates.

Description-Behavior Mismatch

Medium
Confidence
96% confidence
Finding
The skill documents a generic proxy facility that can send arbitrary requests, including POST, PUT, PATCH, and DELETE, while the manifest presents the skill as interacting with API Sports data. This creates a capability mismatch: an agent using the skill could perform broad, potentially state-changing operations through Membrane rather than being limited to read-only sports queries, which materially increases abuse potential if parameters are influenced by user or model error.
