CVE-2026-30822: Flowise: Mass Assignment in `/api/v1/leads` Endpoint

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 13.4% (FIRST EPSS); higher than 96.4% of all records.
  • This probability rose by 13 points in the last 7 days.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: FlowiseAI Flowise 3.0.13.

Low priority for now. Upgrade to FlowiseAI Flowise 3.0.13 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.0.13, unauthenticated users can inject arbitrary values into internal database fields when creating leads. This issue has been patched in version 3.0.13.
