Detailsinfo

A vulnerability, which was classified as problematic, was found in run-llama llama_index up to 0.11.6. Affected is the function BGEM3Index.load_from_disk of the file llama_index/indices/managed/bge_m3/base.py. The manipulation with an unknown input leads to a deserialization vulnerability. CWE is classifying the issue as CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was presented by LifeTeam2024. The advisory is available at huntr.com. This vulnerability is traded as CVE-2024-14021 since 01/09/2026. The exploitability is told to be easy.
