{"id":"CVE-2026-73408","aliases":["GHSA-2xgg-r2wc-c5r2"],"url":"https://o3.security/vulnerability/CVE-2026-73408","summary":"Budibase: MySQL DESCRIBE Backtick Injection via multipleStatements in Database Connector","details":"Budibase is an open-source low-code platform. Prior to 3.39.18, packages/server/src/integrations/mysql.ts enabled multipleStatements and inserted an unescaped tableName into a DESCRIBE statement. An attacker able to create a MySQL table with a backtick and stacked statement in its name could wait for a Budibase administrator to run schema discovery, causing the second statement to execute. The fix applies quoteMySqlIdentifier before constructing the query. This issue is fixed in version 3.39.18.","published":"2026-08-13T22:04:53.979Z","modified":"2026-08-15T04:07:14.329092403Z","cvss":{"score":7.6,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"@budibase/server","fixedVersion":null}],"fix":{"url":"https://github.com/Budibase/budibase/commit/d232bd92144c768884ff8c48cb2e28673d9ffde0","label":"Budibase/budibase@d232bd9"},"references":[{"type":"FIX","url":"https://github.com/Budibase/budibase/commit/d232bd92144c768884ff8c48cb2e28673d9ffde0"},{"type":"FIX","url":"https://github.com/Budibase/budibase/pull/18989"},{"type":"WEB","url":"https://github.com/Budibase/budibase/releases/tag/3.39.18"},{"type":"ADVISORY","url":"https://github.com/Budibase/budibase/security/advisories/GHSA-2xgg-r2wc-c5r2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73408.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73408"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-15T04:07:14.329092403Z"}}
