CVE-2026-114490: Incorrect Authorization in hMailServer

HighCVSS 7.8 · v3.1—No exploit No fix recorded

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.10% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Incorrect authorization in the COM administration API of Progressive Robot hMailServer 6.3.4 through 6.3.6 allows an account assigned the serveradmin role with a list of domains - a credential an administrator may create meaning to confine it to those domains - to act as the whole-server administrator over COM. Administrator roles are meant to confine such a credential to the domains its list names, and the REST API did not take it for the server administrator, but the COM API's server-administrator check read the administer_server permission as the whole server whatever list the grant carried. So the credential signed in through the Control Panel, or through a script run on the server, as the server administrator of every domain: it could read and change every domain's accounts and mail, rename any domain, map a domain alias onto any, write the server's settings and secrets, and create further server-administrator accounts. The COM API's domain-administrator check, asked with no domain, likewise let an account assigned the domainadmin role with a list of domains that leaves out the account's own domain administer that domain's ordinary accounts over COM. An account holding serveradmin with no list is the server administrator by design and is unaffected, as are the help desk, auditor and custom roles.
