{"cve":"CVE-2026-45717","nvd":{"published":"2026-05-27T18:16:25.727","modified":"2026-06-17T10:52:29.813","status":"Deferred","description":"Budibase is an open-source low-code platform. Prior to 3.38.1, Budibase exposes a REST API for datasource management. The route PUT /api/datasources/:datasourceId is registered in the authorizedRoutes group with TABLE/READ permission. This is the same authorization level as the read endpoint (GET /api/datasources/:datasourceId). Every authenticated Budibase app user with the BASIC built-in role or higher carries TABLE/WRITE (and therefore TABLE/READ) permissions, and the datasource update controller performs no additional builder check. As a result, any authenticated non-builder app user can submit a PUT request to rewrite a datasource's config object — including the connection host, port, database credentials, or the base url of a REST datasource. Because no network-level SSRF protection is applied to SQL driver connections, redirecting a PostgreSQL/MySQL/MongoDB datasource to an internal IP address succeeds and the attacker can probe or interact with internal services on arbitrary ports. This vulnerability is fixed in 3.38.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-862"],"references":["https://github.com/Budibase/budibase/releases/tag/3.38.1","https://github.com/Budibase/budibase/security/advisories/GHSA-44m2-crh7-f4q2","https://github.com/Budibase/budibase/security/advisories/GHSA-44m2-crh7-f4q2"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-45717","score":0.00251,"percentile":0.16542,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-44m2-crh7-f4q2","url":"https://osv.dev/vulnerability/GHSA-44m2-crh7-f4q2","summary":"Budibase: `PUT /api/datasources/:datasourceId` is protected only by `TABLE/READ` permission instead of builder access, allowing any authenticated app user to overwrite datasource connection parameters including host, port, and URL","modified":"2026-09-10T03:51:04.536789526Z","packages":[{"ecosystem":"npm","name":"@budibase/server","purl":"pkg:npm/%40budibase/server","ranges":["<3.38.1"],"fixed":["3.38.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
