gcc (Git Context Controller) — agentic threat model

9.0AIVSS 9.0 · Critical

GCC introduces significant security risks by executing a local shell script (gcc_init.sh) and performing direct file system operations to manage versioned memory, making it vulnerable to arbitrary code execution and memory poisoning if not strictly sandboxed.

OWASP AIVSS score rationale

AIVSS = (CVSS_Base + AARS) × Mitigation_Factor, where AARS = (10 − CVSS_Base) × (Factor_Sum / 10) × ThM

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.

L1 · Foundation Models⚠ not certain from listing

Not certain from the listing — The GCC tool is model-agnostic and does not specify or bundle a foundation model, though the underlying LLM's susceptibility to prompt injection could lead to unauthorized git-like operations.

L2 · Data Operations✓ mapped

Directly manages agent memory as a versioned file system under .GCC/. This introduces risks of memory poisoning, unauthorized state restoration (e.g., reverting to an insecure state), and data exfiltration of sensitive context stored in history.

L3 · Agent Frameworks✓ mapped

Provides powerful tools (COMMIT, BRANCH, MERGE, CONTEXT) to the agent framework. If the orchestration framework lacks strict validation, an agent could be manipulated into executing arbitrary git-like operations or corrupting its own state.

L4 · Deployment & Infrastructure✓ mapped

High risk at the infrastructure layer due to the execution of a bundled shell script (scripts/gcc_init.sh) on first use. Without strict containerization or sandboxing, this script execution could lead to local privilege escalation or host compromise.

L5 · Evaluation & Observability⚠ not certain from listing

Not certain from the listing — There is no mention of logging, monitoring, or guardrails to detect anomalous branch/merge operations or unauthorized modifications to the .GCC/ directory.

L6 · Security & Compliance (cross-cutting)⚠ not certain from listing

Not certain from the listing — The tool does not define access control policies, authentication mechanisms, or compliance boundaries for determining which agents or users can trigger context restoration.

L7 · Agent Ecosystem⚠ not certain from listing

Not certain from the listing — While cross-session context recovery could be abused in multi-agent environments to propagate poisoned state, the listing does not explicitly detail multi-agent coordination features.
