MindsDB 25.9.1.1 Path Traversal (CVE‑2026‑27483) Enables Remote Code Execution

MindsDB 25.9.1.1 Path Traversal (CVE‑2026‑27483) Enables Remote Code Execution

What Happened – A path‑traversal flaw (CVE‑2026‑27483) in MindsDB versions < 25.9.1.1 lets an unauthenticated attacker read arbitrary files on the host filesystem and, by chaining the traversal with a malicious Python package, achieve remote code execution. A proof‑of‑concept exploit was published on Exploit‑DB on 2026‑05‑04.

Why It Matters for TPRM –

• The vulnerability resides in a widely‑used AI/ML platform that many third‑party vendors embed in their services.
• Successful exploitation can lead to full compromise of the host environment, exposing downstream data pipelines and customer data.
• Patch availability (≥ 25.9.1.1) may not be uniformly applied across managed services, creating a hidden supply‑chain risk.

Who Is Affected – SaaS providers, data‑analytics platforms, and any organization that runs MindsDB on‑premise or in cloud containers (technology, finance, healthcare, etc.).

Recommended Actions –

• Inventory all assets running MindsDB < 25.9.1.1.
• Apply the official upgrade to 25.9.1.1 or later immediately.
• Verify that file‑system permissions restrict access to the Python site‑packages directory.
• Conduct penetration testing or code‑review to confirm the traversal vector is mitigated.

Technical Notes – The exploit abuses the /api/handlers/ endpoint to inject a crafted path (../../../../../../venv/lib/python3.10/site-packages/pip/__init__.py). Once the file is overwritten, the attacker can execute arbitrary Python code, achieving RCE. No CVE‑specific mitigations were disclosed beyond the version bump. Source: Exploit‑DB 52547
