Flowise - Authentication Bypass (CVE-2026-30824)

CVE-2026-30824 is an authentication bypass vulnerability in Flowise prior to version 3.0.13, where the NVIDIA NIM router endpoints were improperly whitelisted, allowing unauthenticated users to access sensitive container management and token generation features. This flaw could be exploited by remote attackers to gain unauthorized control over privileged operations, posing significant security risks to affected deployments.

CrowdSec has been tracking this vulnerability and its exploits since 22nd of May 2026.

CrowdSec network observations suggest that most exploitation of CVE-2026-30824 involves focused reconnaissance to identify viable targets. Attackers typically tailor their campaigns based on system exposure and configuration. It is unlikely that a given attack is accidental. CrowdSec network telemetry also shows that exploitation of CVE-2026-30824 has significantly declined over the past week. Attack volumes are well below the long-term average, suggesting attackers are rapidly losing interest. The vulnerability appears to be falling out of active use across most threat landscapes.

Attackers exploit unauthenticated access to endpoints under /api/v1/nvidia-nim/, such as /api/v1/nvidia-nim/get-token, to obtain privileged tokens or manage containers without authentication.
