# Unpinned dependencies

> requirements.txt uses unpinned or wildcard versions enabling supply chain substitution

requirements.txt uses unpinned or wildcard versions enabling supply chain substitution

## How to resolve

Pin all dependency versions with == in requirements files. Use a lock file to ensure reproducible builds. Run dependency scanning in CI.

## Risk

**Governance/Compliance**

This vulnerability falls under [ASI04:2026 — Agentic Supply Chain Vulnerabilities](https://genai.owasp.org/resource/owasp-top-10-for-agentic-applications-for-2026/) in the OWASP Top 10 for Agentic Applications. Compromised runtime components — tools, plugins, MCP servers, deps — alter agent behavior.

**Security**

requirements.txt uses unpinned or wildcard versions enabling supply chain substitution. If exploited, this can compromise the agent's integrity, confidentiality, or availability, potentially affecting downstream systems and data.

## Explanation

requirements.txt uses unpinned or wildcard versions enabling supply chain substitution. This falls under ASI04 (Agentic Supply Chain Vulnerabilities): Compromised runtime components — tools, plugins, MCP servers, deps — alter agent behavior.

## Specifications

**Trigger**

* Agent scan detects requirements.txt uses unpinned or wildcard versions enabling supply chain substitution

The scanner looks for patterns such as:

* > \= version constraint on AI framework package
* \~= or \* version in requirements
* no version pin on crewai, langchain, openai, anthropic

**Severity**

* HIGH

**Applies to**: Agent
