PR Review Canvas — agentic threat model
PR Review Canvas is a low-autonomy visualization tool that poses moderate security risks primarily centered around source code confidentiality and indirect prompt injection via malicious pull-request diffs.

MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Not certain from the listing — likely relies on Cursor's underlying LLM APIs. The primary threat is indirect prompt injection, where malicious code comments within a PR diff manipulate the model to misclassify changes or hide backdoors.
Not certain from the listing — processes transient git diffs and PR metadata. The main risk is the potential exfiltration of proprietary source code if diff data is transmitted to external LLM endpoints without adequate privacy guarantees.
Not certain from the listing — orchestration is likely a simple script parsing diffs and calling APIs. Vulnerabilities could arise from insecure parsing of git diffs or command injection if git commands are constructed dynamically.
Runs locally as a Cursor IDE plugin. The primary threat is the compromise of the local developer environment or unauthorized access to local SSH/Git credentials if the plugin is compromised.
Not certain from the listing — no built-in evaluation or logging mechanisms are described. Hallucinations in code explanations could mislead reviewers into approving malicious or buggy code.
Not certain from the listing — relies on the host IDE (Cursor) and user's local Git configuration for authentication and access control to repositories.
Not certain from the listing — operates as a standalone IDE extension with no explicit multi-agent or marketplace interactions described beyond standard plugin distribution.
