Code execution via unsafe pickle deserialization
Published Jul 13, 2026 · Updated Jul 13, 2026
Unsafe deserialization in Akari Asai SELF-RAG at commit 1fcdc420e48f50a7d7ab1ece5494221b93252e99 allows attackers to execute code. Indexer.deserialize_from passes index_meta.faiss directly to pickle.load before its post-load length assertion can validate the data. Exploitation requires cached-index loading to be enabled and attacker control of the cache directory, and code runs with the SELF-RAG process privileges.
