{"id":"CVE-2026-53557","summary":"SQLBot: Second-Order SQL Injection via Excel Datasource Leading to Remote Command Execution","details":"SQLBot is an intelligent Text-to-SQL system based on large language models and RAG. Prior to 1.9.0, an authenticated user can supply a crafted sheet[\"tableName\"] value in the Excel datasource configuration submitted through POST /api/v1/datasource/, and SQLBot stores that value without safe identifier handling. When the same datasource is later removed through DELETE /api/v1/datasource/{id}, the stored value is interpolated into datasource cleanup SQL and executed by PostgreSQL. This second-order SQL injection can invoke PostgreSQL COPY TO PROGRAM and execute arbitrary operating-system commands with the privileges of the postgres process inside the SQLBot container. This issue is fixed in version 1.9.0.","aliases":["GHSA-vxwj-843f-9c9g"],"modified":"2026-09-19T03:46:26.810518645Z","published":"2026-09-17T21:41:45.155Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53557.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-89"]},"references":[{"type":"WEB","url":"https://github.com/dataease/SQLBot/releases/tag/v1.9.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53557.json"},{"type":"ADVISORY","url":"https://github.com/dataease/SQLBot/security/advisories/GHSA-vxwj-843f-9c9g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53557"},{"type":"FIX","url":"https://github.com/dataease/SQLBot/commit/5d5a92a5266e62da7de4a84ffc8317498497b193"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dataease/sqlbot","events":[{"introduced":"0"},{"fixed":"5d5a92a5266e62da7de4a84ffc8317498497b193"},{"fixed":"7637ab391d4a3d2c910c8e265033b155d5c8fea9"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.9.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.8.0","v1.7.0","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.1","v1.2.0","v1.1.4","v1.1.3","v1.1.2","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53557.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
