CVE-2024-3271Public exploitNetwork attack vector

Remote code execution via permissive safe_eval built-ins

Published Apr 16, 2024 · Updated Aug 1, 2024

Command injection in LlamaIndex before 0.10.24 allows remote attackers to execute arbitrary code through generated expressions. The safe_eval function evaluates generated Python after an AST check that blocks private or dunder names but leaves dangerous built-ins such as getattr available. Exploitation requires an application to pass attacker-influenced or model-generated code into safe_eval; successful input runs with the hosting process's permissions.
