Capital One Releases VulnHunter: Open-Source AI Vulnerability Scanner

Financial services giant Capital One has open-sourced 'VulnHunter' under the Apache 2.0 license. VulnHunter is an internally developed agentic AI security scanner designed to analyze complex enterprise codebases for exploitable software vulnerabilities before code reaches production.

Agentic Static Code Analysis in Production

Unlike traditional static analysis (SAST) tools that generate high volumes of false positives, VulnHunter deploys autonomous LLM reasoning agents to construct full exploit control-flow graphs, demonstrating exactly how an attacker could reach vulnerable methods.

Automating Security Remediation for Developers

In addition to identifying security vulnerabilities, VulnHunter automatically generates pull requests containing validated code patches, reducing vulnerability remediation timelines from weeks to minutes.

Developers and security teams can inspect, clone, and integrate VulnHunter into their CI/CD pipelines directly via GitHub, marking a major contribution from the financial industry to open-source software security.
