Summary: n8n: Domain-Restriction Bypass via Unguarded Model-Search Endpoint in OpenAI Chat Model Node
Details: n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the OpenAI Chat Model node enforced credential allowed-domain restrictions for normal calls but not for the model-search dropdown. A workflow editor could set options.baseURL to an arbitrary host and make the searchModels path send the openAiApi credential there. The affected implementation is packages/@n8n/nodes-langchain/nodes/llms/LMChatOpenAi/methods/loadModels.ts, which omitted assertOpenAiCredentialAllowsUrl. This issue is fixed in versions 1.123.76, 2.37.7 and 2.38.2.
