CVE-2026-34400 at a Glance
How to Fix CVE-2026-34400
To remediate this vulnerability, upgrade all affected Alerta server dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
pip install alerta-server>=9.1.0Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show alerta-serverHow to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2026-34400, inspect your installed packages using pip:
pip show alerta-serverAnalyze the terminal output to locate any version of Alerta server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.1.0), your application is affected.
Note: The pip show alerta-server command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Alerta server, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Impact\nThe 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.\n\n### Patches\nFixed 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.\n\n### Workarounds\nUpgrade to v9.1.0 or later. If unable to upgrade, deploy a proxy in front of the Alerta API to sanitize the q= parameter.\n\n### Resources\nhttps://github.com/alerta/alerta/pull/712/files\nhttps://owasp.org/www-community/attacks/SQL_Injection",
