{"id":"CVE-2026-53556","summary":"SQLBot: Authenticated SQL Injection in previewData Resulting in Arbitrary File Read","details":"SQLBot is an intelligent Text-to-SQL system based on large language models and RAG. Prior to 1.9.0, the POST /api/v1/datasource/previewData endpoint in backend/apps/datasource/crud/datasource.py incorporates the client-controlled table_name value into generated SQL without safe identifier handling. An authenticated user can configure a datasource for SQLBot's internal PostgreSQL service and submit a crafted table_name that remains a SELECT operation under the read-only policy while invoking pg_read_file(), pg_read_binary_file(), or pg_ls_dir(). In the default tested trusted loopback authentication configuration, the internal connection accepts invalid credentials and executes with PostgreSQL superuser privileges, allowing filesystem content such as /etc/hosts and /etc/passwd to be returned in the previewData API response and potentially exposing configuration, credentials, authentication secrets, and source code. This issue is fixed in version 1.9.0.","aliases":["GHSA-vwjq-5h4h-x8g5"],"modified":"2026-09-19T11:30:51.722414640Z","published":"2026-09-17T21:39:44.056Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-89"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53556.json"},"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-2026-53556.json"},{"type":"ADVISORY","url":"https://github.com/dataease/SQLBot/security/advisories/GHSA-vwjq-5h4h-x8g5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53556"},{"type":"FIX","url":"https://github.com/dataease/SQLBot/commit/76b5176b0e394740fd07c0d1769c0c792e8cb3b4"},{"type":"FIX","url":"https://github.com/dataease/SQLBot/pull/1156"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dataease/sqlbot","events":[{"introduced":"0"},{"fixed":"76b5176b0e394740fd07c0d1769c0c792e8cb3b4"},{"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-2026-53556.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:N/VA:N/SC:N/SI:N/SA:N"}]}
