CVE-2026-105145: Weaviate Verba unauthenticated API key exfiltration in generate_stream

CVE-2026-105145 · Severity: medium · CVSS 5.3 · Published 2026-10-04

Weaviate Verba is a retrieval-augmented generation (RAG) system that integrates with LLM providers. An unauthenticated attacker can trick the server into revealing stored API keys (such as OpenAI credentials) by sending a malicious configuration to the /ws/generate_stream endpoint, allowing credential theft and unauthorized use of the victim's LLM provider account.

Vendors: Weaviate.

Technical details

The /ws/generate_stream WebSocket endpoint accepts unauthenticated client connections and processes user-supplied RAG generator configurations without validating authentication or the origin. When an attacker supplies a custom OpenAI-compatible base URL and omits the API key field, the get_environment() function falls back to reading the real key from the process environment (OPENAI_API_KEY, OPENAI_EMBED_API_KEY, etc.) and sends it via Authorization header to the attacker-controlled URL. This is an authenticated SSRF that leaks live provider secrets, exploitable without authentication or user interaction.

Affected products

Weaviate Verba up to 2.1.3
