0 CVE-2026-107583 is a medium severity vulnerability in Progressive Robot Ltd's hMailServer versions 6.3.2 through 6.3.5. It involves inefficient algorithmic complexity in the webmail message view of the REST API. A remote unauthenticated attacker can exploit this by sending a specially crafted message with HTML referencing a small embedded image many times. When opened, this causes excessive CPU and memory usage, making the webmail, administration console, and REST API unavailable due to resource exhaustion.
