GHSA-M592-CR2F-4QG5

Vulnerability from github – Published: 2026-01-13 00:30 – Updated: 2026-01-13 00:30

Details

LlamaIndex (run-llama/llama_index) versions up to and including 0.11.6 contain an unsafe deserialization vulnerability in BGEM3Index.load_from_disk() in llama_index/indices/managed/bge_m3/base.py. The function uses pickle.load() to deserialize multi_embed_store.pkl from a user-supplied persist_dir without validation. An attacker who can provide a crafted persist directory containing a malicious pickle file can trigger arbitrary code execution when the victim loads the index from disk.

Severity ?

8.4 (High)
