{"id":"CVE-2026-32950","summary":"SQLBot: RCE via SQL Injection in Excel Upload Endpoint","details":"SQLBot is an intelligent data query system based on a large language model and RAG. Versions prior to 1.7.0 contain a critical SQL Injection vulnerability in the /api/v1/datasource/uploadExcel endpoint that enables Remote Code Execution (RCE), allowing any authenticated user (even the lowest-privileged) to fully compromise the backend server. The root cause is twofold: Excel Sheet names are concatenated directly into PostgreSQL table names without sanitization (datasource.py#L351), and those table names are embedded into COPY SQL statements via f-strings instead of parameterized queries (datasource.py#L385-L388). An attacker can bypass the 31-character Sheet name limit using a two-stage technique—first uploading a normal file whose data rows contain shell commands, then uploading an XML-tampered file whose Sheet name injects a TO PROGRAM 'sh' clause into the SQL. Confirmed impacts include arbitrary command execution as the postgres user (uid=999), sensitive file exfiltration (e.g., /etc/passwd, /etc/shadow), and complete PostgreSQL database takeover. This issue has been fixed in version 1.7.0.","aliases":["GHSA-7hww-8rj5-7rmm"],"modified":"2026-04-10T05:42:32.786647Z","published":"2026-03-20T04:14:45.640Z","database_specific":{"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32950.json","cwe_ids":["CWE-78","CWE-89"]},"references":[{"type":"WEB","url":"https://github.com/dataease/SQLBot/releases/tag/v1.7.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32950.json"},{"type":"ADVISORY","url":"https://github.com/dataease/SQLBot/security/advisories/GHSA-7hww-8rj5-7rmm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32950"},{"type":"FIX","url":"https://github.com/dataease/SQLBot/commit/39f2203cec4bb4b0aa541710733fe7608e3d3c48"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dataease/sqlbot","events":[{"introduced":"0"},{"fixed":"39f2203cec4bb4b0aa541710733fe7608e3d3c48"}]},{"type":"GIT","repo":"https://github.com/dataease/sqlbot","events":[{"introduced":"0"},{"fixed":"22e66c490fc67f77b94d71dfdb048270e9b6641a"}]}],"versions":["v1.0.0","v1.1.0","v1.1.2","v1.1.3","v1.1.4","v1.2.0","v1.2.1","v1.3.0","v1.4.0","v1.5.0","v1.6.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-32950.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
