AI-suggested
Users should verify with Progressive Robot Ltd for any official advisories or updates. Until a fix is available, disabling or avoiding the use of MySQL, MariaDB, or PostgreSQL as the backend database for hMailServer may reduce risk. Additionally, disabling greylisting and message indexing features, which are off by default, can limit exposure. Monitoring vendor channels for patches is recommended. No generic mitigations beyond these specific recommendations are advised.
Description
CVE-2026-126617 is a high-severity SQL injection vulnerability in Progressive Robot Ltd's hMailServer versions 6.0.0-B1 through 6.2.18. It affects the database layer when using MySQL, MariaDB, or PostgreSQL as the backend. The vulnerability arises because parameters are not properly bound, allowing crafted input to alter SQL statements executed by the server. This can be triggered by authenticated users sending mail or by unauthenticated remote senders via certain automated server messages. The flaw allows execution of SQL with the database account's privileges, with PostgreSQL allowing multiple statements per call. SQL Server and SQL Server Compact are not affected. No known exploits are reported in the wild, and no patch links are provided.
