CVE-2026-71298
Maestro: sql identifier injection via properties.* search filter and orderby field
A flaw was found in maestro. A remote attacker could exploit a SQL injection vulnerability in the `orderBy` query parameter of its REST API list endpoints. This flaw, which does not require authentication, allows for read-only blind extraction of data from the database.
Fixes and workarounds
Workaround
To mitigate this vulnerability, restrict network access to the `maestro` REST API list endpoints to trusted clients only. Implement firewall rules or network segmentation to limit exposure of the affected service. If the `maestro` service is not essential, consider disabling it.
