Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

llama-index-core versions before 0.13.0 are vulnerable. On Linux, the get_cache_dir() function uses a predictable, hardcoded directory at /tmp/llama_index without adequate security controls. On multi-user systems, a local attacker can exploit this to steal models, poison cached embeddings, or carry out symlink attacks. Upgrade to llama-index-core 0.13.0 or later.

Written 5 Nov 2026.
