Overview
alerta-server is an Alerta server WSGI application
Affected versions of this package are vulnerable to SQL Injection in the q parameter of the query string API due to direct interpolation of user-supplied input into SQL statements using f-strings. An attacker can execute arbitrary SQL commands by crafting malicious input to the q parameter, potentially leading to unauthorized data access or modification.
Note:
This issue affects only users with Postgres backend, MongoDB backend is not affected.
Workaround
This vulnerability can be mitigated by deploying a proxy in front of the API to sanitize the q parameter.
