Assigner: GitHub_M
Reserved: 27.03.2026 Published: 31.03.2026 Updated: 31.03.2026

Alerta is a monitoring tool. Prior to version 9.1.0, the Query string search API (q=) was vulnerable to SQL injection via the Postgres query parser, which built WHERE clauses by interpolating user-supplied search terms directly into SQL strings via f-strings. This issue has been patched in version 9.1.0.
