CVE-2026-34400
EPSS 0.02%alerta-server has potential SQL Injection vulnerability in Query String Syntax (q=) API
描述
### Impact 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. ### Patches Fixed in v9.1.0. The Postgres query parser now uses parameterized queries with %(name)s placeholders passed to psycopg2's cursor.execute(), preventing SQL injection through the ?q= parameter. The MongoDB backend was not affected. ### Workarounds Upgrade to v9.1.0 or later. If unable to upgrade, deploy a proxy in front of the Alerta API to sanitize the q= parameter. ### Resources https://github.com/alerta/alerta/pull/712/files https://owasp.org/www-community/attacks/SQL_Injection
