|---|---|---|---|
| langchain | pip | >= 0, < 0.0.247 | 0.0.247 |
The vulnerability stems from three key patterns: 1) PALChain's code execution through PythonREPL in its _call method, 2) SQLDatabaseChain's direct execution of LLM-generated SQL, and 3) load_prompt's unsafe use of exec() on Python files. The commit explicitly moves these components to 'experimental' due to known CVEs, and their implementations directly execute user-controllable input without adequate sandboxing or validation. The GitHub advisory and CWE-94 classification confirm these are code injection vectors.
