CVE-2025-7647:
Python vulnerability analysis and mitigation
Overview
The llama-index-core package through version 0.12.44 contains a security vulnerability in the get_cache_dir() function that uses a predictable, hardcoded directory path /tmp/llama_index on Linux systems without proper security controls. The vulnerability was discovered and disclosed on September 27, 2025 (NVD).
Technical details
The vulnerability stems from insecure temporary file creation and potential race conditions in the get_cache_dir() function. It is classified under multiple CWE categories including CWE-379, CWE-377, and CWE-367. The CVSS v3.0 base score is 7.3 (High) with the vector string CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L (NVD, Huntr).
Impact
This vulnerability affects Linux deployments where multiple users share the same system. Attackers with local access can potentially steal proprietary models, poison cached embeddings, or conduct symlink attacks (NVD).
Mitigation and workarounds
A fix has been implemented in the llama-index-core repository as evidenced by the commit (Github). Users should upgrade to versions newer than 0.12.44 to mitigate this vulnerability.
