Alphagbm Investment Thesis

Security checks for vulnerabilities and agentic risk

Overview

This skill is mostly coherent for tracking investment theses, but it exposes permanent deletion of financial research records without clear confirmation safeguards.

Review this skill before installing if you keep important investment notes in AlphaGBM. It should only be used with an API key you intend to grant access to your thesis records, and deletion should be treated as permanent unless the service separately provides recovery or server-side safeguards.

Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Findings (4)

Tool Parameter Abuse

High

Category: Tool Misuse
Confidence: 94% confidence
Finding: The skill exposes a destructive DELETE endpoint that accepts only a numeric thesis ID, with no documented guardrails such as ownership verification, confirmation, or constraints on how the ID is sourced. In an agentic context, this creates tool-parameter abuse risk: a mistaken, guessed, stale, or adversarially supplied ID could cause unauthorized or unintended deletion of records.

5. Delete thesis (by id)

text
DELETE /api/research/theses/<THESIS_ID>

Hard-delete. Also uses numeric id.

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 92% confidence
Finding: The trigger phrase "update my thesis" is overly broad and can match ordinary conversation without clearly signaling intent to invoke this skill. In an agent environment, broad activation increases the chance of unintended tool use that can modify investment records or initiate follow-on API actions without sufficiently explicit user intent.
