NVD description
A weakness has been identified in langflow-ai langflow up to 1.10.2. This affects the function eval of the file src/lfx/src/lfx/components/llm_operations/lambda_filter.py 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.
What to do
- NVD lists no fixed version yet: follow the vendor advisory below and keep Langflow off the public internet until a fix ships.
- Do not expose the component's API or UI to the internet without authentication in front of it.
