Budibase Server before 3.41.3 SSRF with Credential Leakage

Noroxi assessment

Priority: Monitor (action score 33/100)

  • 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: 0.30% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: budibase server 3.41.3.

Low priority for now. Upgrade to budibase server 3.41.3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Budibase Server before 3.41.3 contains a server-side request forgery vulnerability in the datasource verify endpoint that allows builder-level users to supply arbitrary URLs without SSRF validation. Attackers can exploit this to leak internal CouchDB credentials by making requests to attacker-controlled servers, gaining full database access in cloud deployments.
