Mystock

Security checks for vulnerabilities and agentic risk

Overview

This stock assistant has a coherent purpose, but it exposes and mutates private portfolio data through an unauthenticated network service and can send financial context and API keys to external AI services.

Review this before installing. Run it only on a trusted local machine or network, avoid exposing port 8000, do not configure AI keys until provider destinations and transmitted data are clear, rotate any real key used with the zhipu option, and remove bundled portfolio/memo data before use or redistribution.

It also sends the current user message, the system prompt, and up to ten conversation-history entries. The configuration guide presents this mode as a Zhipu GLM integration but does not disclose that credentials and messages are sent to this domain. Because the bearer key is reusable authentication material, any service receiving it may use the credential independently until it expires or is revoked. This behavio ...[truncated 1122 chars]

Package installation can execute lifecycle scripts with the privileges of the user running the installer. The startup script performs package-management operations every time the application starts. Startup should be deterministic and should not unexpectedly change the execution environment. The frontend imports unversioned CDN assets. The effective JavaScript executed by the browser may therefore change after the project has been reviewed. No Subresource Integrity attributes are present to verify downloaded content. This is primarily a supply-chain weakness. The audit f ...[truncated 1316 chars]

Missing User Warnings

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

The documentation explicitly instructs users to place an API key directly in source code, which strongly increases the chance the secret will be committed, shared, logged, or exposed through code review and repository access. Hardcoded credentials are long-lived, difficult to rotate safely, and commonly lead to unauthorized API use if leaked.

Known Vulnerable Dependency: fastapi==0.109.0 — 1 advisory(ies): CVE-2024-24762 (FastAPI is a web framework for building APIs with Python 3.8+ based on standard )

High
Category
Supply Chain
Confidence
95% confidence
Finding

The dependency is pinned to FastAPI 0.109.0, which is flagged by the scanner as affected by a published advisory (CVE-2024-24762). In a backend API service, vulnerable framework components are directly exposed to untrusted client input, so a known issue in request handling can materially increase risk of denial of service or related request-processing abuse.

Supply Chain
Confidence
98% confidence
Finding

python-multipart 0.0.6 is reported with numerous advisories, including multipart parsing denial-of-service conditions. In a FastAPI backend, this library is commonly used to process file uploads and form data from remote users, making parser-level ReDoS or resource-exhaustion flaws especially dangerous because they can be triggered pre-authentication with crafted requests.

Finding

This is a markdown file, so SQP-2 applies to missing warnings in the skill description. The README advertises real-time market data, shareholder monitoring, and AI-driven Q&A, and later requires network connectivity, but it does not warn users that their stock queries or related usage data may be sent to external services.

Vague Triggers

Category
Not specified by scanner
Confidence
90% confidence
Finding

The manifest description uses expansive phrases like market analysis, investment research, and portfolio management, which overlap with common user requests that may not require this specific skill. In agent routing systems, such broad language can bias selection toward this skill and lead to over-invocation or misuse beyond its intended stock-data scope.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
88% confidence
Finding

The skill's invocation rules are broad enough to match generic finance or investment discussion, which can cause the agent to trigger this skill outside a clearly scoped stock-analysis request. Overbroad triggering increases the chance of unnecessary tool activation, unintended data access, and user confusion about why a local service or UI-backed workflow is being invoked.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The guide recommends storing an API key in a local .env file but provides no warning to keep that file out of version control, restrict file permissions, or use a secrets manager. This can lead to accidental credential exposure through commits, backups, shared directories, or support bundles.
