CVE-2026-7700 Details
Description
A weakness has been identified in langflow-ai langflow up to 1.8.4. This affects the function eval of the file src/lfx/src/lfx/components/llm_operations/lambda_filter.p of the component LambdaFilterComponent. Executing a manipulation can lead to code injection. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
A code injection vulnerability has been identified in Langflow-AI versions prior to 1.8.4. The issue resides in the LambdaFilterComponent, specifically within the eval function of the lambda_filter.py file. This vulnerability allows for remote code execution by manipulating the input processed by the Smart Transform feature, which enables users to create Python lambdas that are executed without proper validation or sandboxing. The flaw arises from a combination of inadequate input validation, the use of eval() without execution restrictions, and the potential for prompt injection into the language model.
Langflow users are advised to update to version 1.8.4 or later, where this vulnerability has been addressed.
