Title source: llmExploitation Summary
EIP tracks 3 public exploits for CVE-2026-45829. PoCs published by exploitintel, 0xBlackash, fevar54.
AI-analyzed exploit summary This repository contains a functional exploit for CVE-2026-45829, demonstrating pre-authentication remote code execution in ChromaDB's Python backend via unvalidated kwargs passthrough to HuggingFace's `trust_remote_code`. The PoC includes a Docker-based lab environment with a mock HuggingFace Hub and a malicious model to trigger the vulnerability.
Description
A pre-authentication, code injection vulnerability in version 1.0.0 or later of the ChromaDB Python project allows an unauthenticated attacker to run arbitrary code on the server by sending a malicious model repository and trust_remote_code set to true in the /api/v2/tenants/{tenant}/databases/{db}/collections endpoint.
