Budibase is an open-source low-code platform.
CVSS 9.6 Critical EPSS 0.6% · p46
Should you act?
Critical and remotely reachable
No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- Not in CISA KEV, but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.6%, percentile 46: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 46% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Only applies if your dependency tree includes
@budibase/server(npm) <= 3.38.1, no fixed version listed. Check your lockfile, including transitive dependencies.
What it is
Budibase is an open-source low-code platform. Prior to 3.40.0, the MySQL integration component in Budibase is configured with multipleStatements: true, enabling execution of multiple SQL statements in a single query. Attackers can inject malicious SQL commands through user input fields, leading to complete database compromise. This vulnerability is fixed in 3.40.0.
