Prior to version 3.33.4, a server-side request forgery (SSRF) vulnerability exists in Budibase's REST datasource connector. The platform's SSRF protection mechanism (IP blacklist) is rendered completely ineffective because the BLACKLIST_IPS environment variable is not set by default in any of the official deployment configurations. When this variable is empty, the blacklist function unconditionally returns false, allowing all requests through without restriction. This issue has been patched in version 3.33.4.","state":0,"publishedAt":"2026-04-03T16:16:39.8+00:00","modifiedAt":"2026-10-06T22:10:00.247+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","score":9.6,"severity":"CRITICAL"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/Budibase/budibase/commit/5b0fe83d4ece52696b62589cba89ef50cc009732","https://github.com/Budibase/budibase/pull/18236","https://github.com/Budibase/budibase/releases/tag/3.33.4","https://github.com/Budibase/budibase/security/advisories/GHSA-7r9j-r86q-7g45"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-31818","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-918","CWE-1188"],"productCriteria":["cpe:2.3:a:budibase:budibase:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-04-03T16:16:39.800","lastModified":"2026-10-06T22:10:00.247"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
