{"id":"CVE-2026-32950","state":"PUBLISHED","title":"SQLBot: RCE via SQL Injection in Excel Upload Endpoint","description":"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.","publishedAt":"2026-03-20T04:14:45.640Z","updatedAt":"2026-03-24T01:49:10.552Z","severity":{"score":8.6,"label":"High","version":"4.0","vector":"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","source":"GitHub_M"},"assigner":"GitHub_M","products":["dataease SQLBot"],"affected":[{"vendor":"dataease","product":"SQLBot","versions":[{"version":"< 1.7.0","status":"affected"}]}],"references":["https://github.com/dataease/SQLBot/security/advisories/GHSA-7hww-8rj5-7rmm","https://github.com/dataease/SQLBot/commit/39f2203cec4bb4b0aa541710733fe7608e3d3c48","https://github.com/dataease/SQLBot/releases/tag/v1.7.0"],"weaknesses":["CWE-89","CWE-78"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/32xxx/CVE-2026-32950.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-32950","state":"PUBLISHED","datePublished":"2026-03-20T04:14:45.640Z","dateUpdated":"2026-03-24T01:49:10.552Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-03-17T00:05:53.284Z"},"containers":{"cna":{"title":"SQLBot: RCE via SQL Injection in Excel Upload Endpoint","descriptions":[{"lang":"en","value":"SQLBot is an intelligent data query system based on a large language model and RAG.
