Answer in brief
CVE-2026-70478 records a Critical severity (CVSS 9.2) vulnerability in Flowise: Unauthenticated OAuth2 token refresh endpoint returns access tokens — enables token theft for any connected service. The current sources do not mark it as known exploited. The current feed maps FlowiseAI/Flowise (generic), flowise (npm). Check affected ranges and fixed versions before updating.

CVSS is 9.2. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to 3.1.3, the POST /api/v1/oauth2-credential/refresh/:credentialId endpoint is included in WHITELIST_URLS and requires no authentication. The endpoint decrypts the stored credential, sends a refresh request to the configured OAuth provider with the client secret and refresh token, and returns the refreshed access_token in the response body. An attacker with a credential ID can use the token to access the victim's connected service and can also exhaust refresh-token quota. This issue is fixed in 3.1.3.
