CVE-2026-41278: Flowiseai Flowise

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.0, the GET /api/v1/public-chatflows/:id endpoint returns the full chatflow object without sanitization for public chatflows. Docker validation revealed this is worse than initially assessed: the sanitizeFlowDataForPublicEndpoint function does NOT exist in the released v3.0.13 Docker image. Both public-chatflows AND public-chatbotConfig return completely raw flowData including credential IDs, plaintext API keys, and password-type fields. This vulnerability is fixed in 3.1.0.

Affected products

• Flowiseai Flowise: before 3.1.0 (fixed in 3.1.0)
