CVE-2026-7687 Details
Description
A vulnerability was determined in langflow-ai langflow up to 1.8.4. Affected by this issue is the function CodeParser.parse_callable_details of the file src/lfx/src/lfx/custom/code_parser/code_parser.py of the component Full Builtins Module Handler. Executing a manipulation can lead to command injection. The attack can be executed remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.
A command injection vulnerability exists in Langflow AI versions through 1.8.4, specifically within the Full Builtins Module Handler. The issue arises in the CodeParser.parse_callable_details function, located in src/lfx/src/lfx/custom/code_parser/code_parser.py. The vulnerability allows remote code execution by exploiting the eval() function, which executes unvalidated strings as Python code. This exploitation is possible because the evaluation environment does not restrict access to built-in functions, enabling the execution of arbitrary commands.
Users can update to Langflow version 1.8.5 or later, where this vulnerability has been fixed.
