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
Improper validation of specified type of input vulnerability in Magarsus Consulting Ltd. Co. IDM-MFA allows Authentication Bypass. This issue affects IDM-MFA: from 2025.11.27 before 2026.03.10.

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 · moderate confidence

IDM-MFA by Magarsus Consulting Ltd. Co. contains an improper input validation vulnerability that allows authentication bypass. The vulnerability stems from inadequate validation of a specific input type within the MFA authentication flow. An attacker could potentially bypass authentication mechanisms by supplying improperly validated input data.

MitigationUpgrade IDM-MFA to version 2026.03.10 or later. Until patched, restrict network access to the authentication endpoints and implement additional monitoring on authentication attempts.

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 IDM-MFA installed version
    Check the product's About page, version file, or run 'idm-mfa --version' if CLI available. Look for version metadata in installation directory.
    Affected if Installed version is earlier than 2026.03.10
  2. Verify authentication interface is accessible
    Confirm the login/authentication endpoints are exposed (e.g., /login, /auth, /mfa). Check if web interface or API authentication routes are publicly or internally accessible.
    Affected if Authentication interface is accessible and version is unpatched
  3. Inspect input validation for authentication parameters
    Review authentication request handling code or configuration for the specific input type mentioned in the vulnerability. Look for how user-supplied authentication inputs are validated.
    Affected if Input validation for the affected parameter is missing, weak, or can be bypassed
  4. Check for recent authentication logs
    Review authentication logs for unusual patterns, repeated failed attempts, or successful authentications from unexpected sources.
    Affected if Logs show successful authentications without proper credential validation occurring

User is affected if IDM-MFA version is earlier than 2026.03.10 and authentication interface is accessible without the fixed input validation in place.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade IDM-MFA to version 2026.03.10 or later. Until patched, restrict network access to the authentication endpoints and implement additional monitoring on authentication attempts.

Recommended fix Moderate confidence

IDM-MFA version 2026.03.10 or later

  1. 1. Identify the current installed version of IDM-MFA by checking the system configuration orAbout section
  2. 2. If the installed version is from 2025.11.27 before 2026.03.10, plan for upgrade
  3. 3. Backup the current IDM-MFA configuration and database before proceeding with upgrade
  4. 4. Obtain the updated IDM-MFA version 2026.03.10 or later from Magarsus Consulting Ltd. Co.
  5. 5. Apply the upgrade following vendor-provided installation documentation
  6. 6. After upgrade, verify the authentication mechanism functions correctly
  7. 7. Test that the improper input validation vulnerability is remediated by attempting valid and invalid input scenarios
