CVE-2026-46425: Budibase: SCIM endpoints lack role-based authorization, BASIC users CRUD tenant users

Noroxi assessment

Priority: Monitor (action score 39/100)

  • 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: 0.28% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Budibase budibase 3.38.2.

Low priority for now. Upgrade to Budibase budibase 3.38.2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Budibase is an open-source low-code platform. Prior to 3.38.2, packages/worker/src/api/routes/global/scim.ts attaches only two middlewares to the SCIM router: requireSCIM (checks the Enterprise feature flag and SCIM config) and doInScimContext (sets the SCIM request context). There is no role check. Any authenticated user who reaches the worker (BASIC role, workspace-scoped builder, anyone) can call SCIM endpoints and CRUD every user and group in the tenant. This vulnerability is fixed in 3.38.2.
