CRITICAL 9.6

DescriptionGitHub Advisory

Langroid is a framework for building large-language-model-powered applications. Prior to version 0.59.32, there is a bypass to the fix for CVE-2025-46724. TableChatAgent can call pandas_eval tool to evaluate the expression. There is a WAF in langroid/utils/pandas_utils.py introduced to block code injection CVE-2025-46724. However it can be bypassed due to _literal_ok() returning False instead of raising UnsafeCommandError on invalid input, combined with unrestricted access to dangerous dunder attributes (__init__, __globals__, __builtins__). This allows chaining whitelisted DataFrame methods to leak the eval builtin and execute arbitrary code. This issue has been patched in version 0.59.32.

Executive ViewAI

Why It Matters

Organizations using Langroid versions prior to 0.59.32 are at critical risk due to a bypass vulnerability that circumvents previous security fixes, potentially allowing attackers to execute arbitrary code or access sensitive data. This affects any applications built on the Langroid framework and requires immediate patching to prevent exploitation.

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.
