CVE-2025-7707 is a high-severity vulnerability (CVSS 7.8) affecting llama_index library version 0.12.33, where its default NLTK data directory is world-writable in multi-user environments. This allows local attackers to overwrite, delete, or corrupt NLTK data, potentially causing denial of service, data tampering, or privilege escalation due to a shared, rather than user-specific, cache. While the vulnerability has a high FAUCET Risk Score of 74/100, there is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or community discussion.
