alerta-server has potential SQL Injection vulnerability in Query String Syntax (q=) API
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| PyPI | alerta-server | < 9.1.0 | 9.1.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
