Regulation text

Vulnerabilities in vector databases and embedding stores used by RAG applications. Includes unauthorised access to embedding stores, cross-tenant data leakage in shared embedding spaces, inversion attacks that reconstruct training data from embeddings, poisoned embeddings injected via document upload paths, and weak access control on retrieved-context filtering.

CWEWhy it persistsConfidence
CWE-2871. Improper authentication allows attackers to bypass security measures. This directly leads to unauthorized access to vector databases and embedding stores.
95%
CWE-2841. Improper access control enables unauthorized access to embedding stores. This facilitates cross-tenant data leakage and allows manipulation of retrieved context filtering.
95%
CWE-2001. Exposure of sensitive information to an unauthorized actor results in data leakage. This includes cross-tenant data exposure and enables inversion attacks from embeddings.
90%
CWE-5021. Deserialization of untrusted data can lead to arbitrary code execution. This vulnerability can be exploited during embedding injection via document upload paths.
70%
CWE-7981. Use of hard-coded credentials provides attackers with persistent access. This bypasses authentication for vector databases, enabling unauthorized operations.
80%
CWE-4341. Unrestricted upload of files with dangerous types allows attackers to inject malicious content. This directly leads to poisoned embeddings via document upload paths.
85%
CWE-3061. Missing authentication for critical functions allows unauthorized operations. This includes modifying embedding stores or bypassing retrieved-context filtering without proper checks.
