Summary

LlamaIndex versions up to and including 0.12.2 contain an uncontrolled resource consumption vulnerability in the VannaPack VannaQueryEngine implementation. The custom_query() function generates SQL statements from user-supplied prompts and executes them via vn.run_sql() without enforcing query execution limits, allowing an attacker to trigger expensive SQL operations that exhaust CPU or memory resources.

Risk Assessment

The risk is a potential Denial of Service (DoS) attack where an attacker can send a malicious prompt, causing system unavailability for other users.

Recommendation

Immediately upgrade LlamaIndex to a version later than 0.12.2 and implement query execution limits such as timeout or maximum row count.

Other vulnerabilities in LlamaIndex

CVE-2024-14021High
LlamaIndex versions up to and including 0.11.6 contain an unsafe deserialization vulnerability in BGEM3Index.load_from_disk(). The function uses pickle.load() to deserialize multi_embed_store.pkl from a user-supplied persist_dir without validation, allowing an attacker to execute arbitrary code by providing a crafted pickle file.

Original NVD description (English source)

LlamaIndex (run-llama/llama_index) versions up to and including 0.12.2 contain an uncontrolled resource consumption vulnerability in the VannaPack VannaQueryEngine implementation. The custom_query() logic generates SQL statements from a user-supplied prompt and executes them via vn.run_sql() without enforcing query execution limits In downstream deployments where untrusted users can supply prompts, an attacker can trigger expensive or unbounded SQL operations that exhaust CPU or memory resources, resulting in a denial-of-service condition. The vulnerable execution path occurs in llama_index/packs/vanna/base.py within custom_query().
