CVE-2026-34400

CRITICAL

alerta-server has potential SQL Injection vulnerability in Query String Syntax (q=) API

Title source: cna

Description

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.
