Authenticated code execution via FAISS pickle loading
Published May 1, 2026 · Updated May 1, 2026
Unsafe deserialization in Mem0 1.0.0 through 1.0.11 allows remote authenticated users to execute code through crafted FAISS data. The FAISS vector store's _load() method passes an attacker-controlled .pkl docstore to pickle.load(), which invokes attacker-selected reduction callables. Exploitation requires control of the serialized FAISS docstore; successful payloads run system commands as the Mem0 process.
