CVE-2026-34400: Alerta Project Alerta

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

• Alerta Project Alerta: before 9.1.0 (fixed in 9.1.0)
