CVE-2026-30824: Flowise NVIDIA NIM Authentication Bypass PoC

Unrestricted file upload in Flowise LLM workflow builder before 3.0.13 via /api/v1/attachments endpoint allows unauthenticated attackers to upload and execute malicious files. PoC available.

Privilege escalation in Flowise versions prior to 3.0.13 allows authenticated users to bypass API authorization by spoofing an internal request header, granting access to sensitive administrative functions including API key and credential management. Public exploit code exists for this vulnerability, and an attacker with valid tenant credentials can escalate to administrative privileges without additional authentication. No patch is currently available for affected deployments.

Flowise versions up to 3.0.13 is affected by authorization bypass through user-controlled key (CVSS 8.8).

Flowise versions up to 3.0.13 is affected by improperly controlled modification of dynamically-determined object attributes (CVSS 7.7).
