CVE-2026-86082: n8n

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• n8n n8n: before 1.123.76 (fixed in 1.123.76); from 2.0.0, before 2.37.7 (fixed in 2.37.7); from 2.38.0, before 2.38.2 (fixed in 2.38.2)
