An attacker with DDL rights on a connected MySQL/MSSQL datasource can create a column whose name contains a backtick (MySQL) or single quote (MSSQL) plus additional SQL; Budibase's schema introspection stores the name verbatim, and when a Budibase builder later renames that column through the UI (POST /api/tables with _rename.old), the embedded quote character terminates the identifier and the injected SQL is executed. Because the MySQL connection is opened with multipleStatements: true, stacked statements run as Budibase's datasource user, allowing arbitrary reads, writes, or destructive operations on the connected database outside Budibase's row/table permission model. Fixed in 3.45.0."}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')", "cweId": "CWE-89", "type": "CWE"}]}], "affected": [{"vendor": "budibase", "product": "server", "defaultStatus": "unaffected", "packageURL": "pkg:npm/budibase/server", "versions": [{"version": "0", "status": "affected", "versionType": "semver", "lessThan": "3.45.0"}, {"version": "3.45.0", "status": "unaffected", "versionType": "semver"}]}], "metrics": [{"format": "CVSS", "cvssV4_0": {"version": "4.0", "vectorString": "CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H", "attackVector": "NETWORK", "attackComplexity": "HIGH", "attackRequirements": "PRESENT", "privilegesRequired": "LOW", "userInteraction": "PASSIVE", "vulnConfidentialityImpact": "HIGH", "vulnIntegrityImpact": "HIGH", "vulnAvailabilityImpact": "HIGH", "subConfidentialityImpact": "HIGH", "subIntegrityImpact": "HIGH", "subAvailabilityImpact": "HIGH", "baseScore": 8.9, "baseSeverity": "HIGH"}}, {"format": "CVSS", "cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H", "attackVector": "NETWORK", "attackComplexity": "HIGH", "privilegesRequired": "LOW", "userInteraction": "REQUIRED", "scope": "CHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 8, "baseSeverity": "HIGH"}}], "references": [{"url": "https://github.com/Budibase/budibase/security/advisories/GHSA-ppj8-hmx2-m546", "tags": ["vendor-advisory"], "name": "GitHub Security Advisory (GHSA-ppj8-hmx2-m546)"}, {"name": "VulnCheck Advisory: Budibase before 3.45.0 SQL Injection via column-rename DDL", "tags": ["third-party-advisory"], "url": "https://www.vulncheck.com/advisories/budibase-before-3.45.0-sql-injection-via-column-rename-ddl"}], "credits": [{"lang": "en", "value": "manus-use", "type": "reporter"}], "x_generator": {"engine": "vulncheck-endgame"}}}}
