Notes: Only affects deployments using DuckDBVectorStore with the vulnerable delete function.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to complete system compromise, data theft, and lateral movement within the network.

🟠

Likely Case

Arbitrary file read/write allowing sensitive data exposure, configuration file modification, or database manipulation.

🟢

If Mitigated

Limited impact with proper input validation and database permissions restricting file system access.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploit details available in public bounty reports; SQL injection to file operations is well-documented.
