CVE-2026-45715: Budibase: SSRF Bypass via HTTP Redirect in REST Datasource Integration

HighCVSS 7.7 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 0.25% (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 3.38.1.

Low priority for now. Upgrade to Budibase budibase 3.38.1 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 3.38.1, the REST datasource integration (packages/server/src/integrations/rest.ts) follows HTTP redirects without re-checking the IP blacklist, allowing an authenticated Builder to access internal services (cloud metadata, databases) by redirecting through an attacker-controlled server. This vulnerability is fixed in 3.38.1.
