CVE-2026-53554: SQLBot arbitrary code execution through parseExcel upload endpoint

Summary

CVE-2026-53554 affects SQLBot, a Text-to-SQL system built on large language models and RAG, prior to 1.9.0. The POST /api/v1/datasource/parseExcel endpoint trusts attacker-controlled multipart filenames when choosing storage, and it writes uploaded content before spreadsheet parsing and validation finish. A crafted upload can plant a Python file in /opt/sqlbot/app/alembic/versions/ even when parsing fails and the endpoint returns an error. On the next startup or migration, Alembic imports that file and runs its module-level statements inside the SQLBot runtime.

Mitigation

Fixed in 1.9.0.
