Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Denial of service condition in M-Files Server in versions before 25.1.14445.5 allows an unauthenticated user to consume computing resources in certain conditions.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

M-Files Server versions prior to 25.1.14445.5 contain a denial of service vulnerability where an unauthenticated remote attacker can cause excessive resource consumption, likely through malformed or repeated requests that trigger computationally expensive operations.

MitigationUpgrade M-Files Server to version 25.1.14445.5 or later to remediate this vulnerability. Consider implementing rate limiting or network-level controls as additional defense-in-depth while planning the upgrade.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify M-Files Server installation
    Check the M-Files Server version by logging into M-Files Admin, selecting the server vault, and viewing the version information in the server properties. Alternatively, check the 'About' dialog in the M-Files desktop client or use the M-Files Server Information tool if available.
    Affected if The installed version is lower than 25.1.14445.5
  2. Verify version from server directly
    Access the M-Files Server administration interface or check the installation directory for version metadata. On Windows, the version can often be retrieved via file properties of the M-Files Server executable.
    Affected if The version displayed is < 25.1.14445.5
  3. Confirm network exposure
    Determine if the M-Files Server is accessible from untrusted networks. Check firewall rules, VPN configurations, and whether the server is exposed to the internet or untrusted internal segments.
    Affected if The server is network-accessible from unauthenticated clients or untrusted networks and the version is below 25.1.14445.5
  4. Review server logs for resource anomalies
    Examine M-Files Server logs for signs of excessive resource consumption, repeated failed requests, or unusual request patterns that may indicate exploitation attempts.
    Affected if Logs show sustained high CPU, memory usage, or repeated malformed requests and the version is below 25.1.14445.5

A user is affected if their M-Files Server version is below 25.1.14445.5 and the server is accessible to unauthenticated remote attackers.
