Focus on hmailserver vulnerabilities and metrics.
Last updated: 25 Nov 2025, 23:25 UTC
This page consolidates all known Common Vulnerabilities and Exposures (CVEs) associated with hmailserver. We track both calendar-based metrics (using fixed periods) and rolling metrics (using gliding windows) to give you a comprehensive view of security trends and risk evolution. Use these insights to assess risk and plan your patching strategy.
For a broader perspective on cybersecurity threats, explore the comprehensive list of CVEs by vendor and product. Stay updated on critical vulnerabilities affecting major software and hardware providers.
Total hmailserver CVEs: 4
Earliest CVE date: 14 Aug 2008, 19:41 UTC
Latest CVE date: 21 Jul 2025, 16:15 UTC
Latest CVE reference: CVE-2025-52374
30-day Count (Rolling): 0
365-day Count (Rolling): 3
Calendar-based Variation
Calendar-based Variation compares a fixed calendar period (e.g., this month versus the same month last year), while Rolling Growth Rate uses a continuous window (e.g., last 30 days versus the previous 30 days) to capture trends independent of calendar boundaries.
Month Variation (Calendar): 0%
Year Variation (Calendar): 0%
Month Growth Rate (30-day Rolling): 0.0%
Year Growth Rate (365-day Rolling): 0.0%
Average CVSS: 1.38
Max CVSS: 4.3
Critical CVEs (≥9): 0
| Range | Count |
|---|---|
| 0.0-3.9 | 4 |
| 4.0-6.9 | 1 |
| 7.0-8.9 | 0 |
| 9.0-10.0 | 0 |
These are the five CVEs with the highest CVSS scores for hmailserver, sorted by severity first and recency.
Use of hardcoded cryptographic key in Encryption.cs in hMailServer 5.8.6 and 5.6.9-beta allows attacker to decrypt passwords to other servers from hMailAdmin.exe.config file to access other hMailServer admin consoles with configured connections.
Use of hardcoded cryptographic key in BlowFish.cpp in hMailServer 5.8.6 and 5.6.9-beta allows attacker to decrypt passwords used in database connections from hMailServer.ini config file.
An issue in hMailServer v.5.8.6 allows a local attacker to obtain sensitive information via the hmailserver/installation/hMailServerInnoExtension.iss and hMailServer.ini components.
HMailServer 5.3.x and prior: Memory Corruption which could cause DOS
Unspecified vulnerability in the IMAP server in hMailServer 4.4.1 allows remote authenticated users to cause a denial of service (resource exhaustion or daemon crash) via a long series of IMAP commands.
