## Summary

GitHub’s Security Lab released **Fuzzing Taskflow**, an autonomous pipeline for vulnerability discovery in C/C++ repositories. By specifying a GitHub repo, the system—built on its **Taskflow Agent**—handles entry-point identification, harness creation, AFL++ execution, crash triage, and report generation without human input. The lab reported in January 2026 that the underlying agent framework had already found **30 real vulnerabilities** during CodeQL alert triage, though it emphasized fuzzing remains no substitute for human oversight.

The tool separates decision-making (handled by LLM agents) from execution (via MCP tools like AFL and clang). It iteratively improves coverage by doubling time budgets (from **30 seconds to 960 seconds**) and halting when growth plateaus. GitHub notes the pipeline generates vulnerability reports but does not patch them. Availability, pricing, and regional restrictions are unspecified.

## Key points

- GitHub Security Lab’s Fuzzing Taskflow automates C/C++ fuzzing end-to-end with AI agents, from harness creation to report generation
- Built on Taskflow Agent framework, which previously found 30 real vulnerabilities during CodeQL triage in 2026
- Separates LLM decision-making from tool execution (AFL++, clang) and uses coverage feedback loops with time budgets up to 960 seconds

## Why it matters

Reduces human labor in fuzzing for C/C++ projects, lowering barriers for teams lacking security expertise to run continuous vulnerability discovery.
