Exploitation Summary
EIP tracks 1 public exploit for CVE-2026-5366. PoCs published by renat0z3r0.
AI-analyzed exploit summary This repository contains a functional exploit PoC for CVE-2026-5366, demonstrating a Git argument injection vulnerability in Prefect 3.6.23. The exploit leverages the `commit_sha` parameter to achieve RCE via `--upload-pack` injection, with detailed technical analysis and a network-free testing script.
Description
Prefect version 3.6.23 is vulnerable to remote code execution due to improper handling of user-controlled input in the `GitRepository` storage class. The `commit_sha` parameter, which is passed to git commands, lacks validation and does not include a `--` separator to distinguish user input from git flags. This allows attackers to inject arbitrary git flags, such as `--upload-pack`, enabling execution of external programs. Additionally, the `directories` parameter can be exploited to inject git flags during sparse-checkout operations. These vulnerabilities allow any user with deployment creation permissions to execute arbitrary commands on worker machines, compromising shared work pools in multi-tenant environments.
