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
A improper authentication vulnerability in Fortinet FortiSOAR PaaS 7.6.0 through 7.6.3, FortiSOAR PaaS 7.5.0 through 7.5.2, FortiSOAR on-premise 7.6.0 through 7.6.3, FortiSOAR on-premise 7.5.0 through 7.5.2 may allow an unauthenticated attacker to bypass authentication via replaying captured 2FA request. The attack requires being able to intercept and decrypt authentication traffic and precise timing to replay the request before token expiration, which raises the attack complexity.

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

This is an improper authentication vulnerability in Fortinet FortiSOAR where an unauthenticated attacker can bypass 2FA by replaying a captured 2FA authentication request. Successful exploitation requires the attacker to perform a man-in-the-middle attack to intercept and decrypt authentication traffic, then precisely time the replay of the 2FA request before the token expires.

MitigationUpgrade to FortiSOAR versions 7.6.4 or later (or latest available) which contain the patch for this vulnerability. Additionally, enforce network-level protections such as VPN usage and TLS inspection to make man-in-the-middle attacks more difficult.

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 if FortiSOAR is deployed
    Check for FortiSOAR installation by reviewing installed software on systems or checking for FortiSOAR services running on the network. Common installation paths include /opt/fortisoar/ or check for 'fortisoar' processes via 'ps aux | grep fortisoar' on Linux systems.
    Affected if FortiSOAR is installed and running in the environment
  2. Determine installed FortiSOAR version
    Log into the FortiSOAR admin UI and navigate to Settings > System > About, or use the command line: 'cd /opt/fortisoar && ./docker-compose exec -T fsapp cat /opt/fortisoar/version.json' (adjust path based on installation method).
    Affected if Version is 7.5.0 through 7.5.2, or 7.6.0 through 7.6.3
  3. Verify 2FA is enabled
    In FortiSOAR admin UI, go to Settings > Users > Authentication Profile, or check configuration files for 2FA/multi-factor authentication settings. Look for TOTP, SMS, or email-based 2FA configurations.
    Affected if Two-factor authentication is configured and active for any user accounts
  4. Assess network exposure to MITM attacks
    Review network architecture to determine if FortiSOAR login endpoints are accessible over untrusted networks without VPN or TLS inspection protections. Check if SSL/TLS interception is not enforced for authentication traffic.
    Affected if Users can authenticate to FortiSOAR from networks where an attacker could position themselves to intercept traffic (e.g., public networks, untrusted WiFi, or insufficient network segmentation)

The environment is affected if FortiSOAR version is 7.5.0-7.5.2 or 7.6.0-7.6.3, 2FA is enabled, and users can authenticate from networks where a man-in-the-middle attack is feasible.

Upgrade available Upgrade to 7.5.3 / 7.6.4 or later
Fixed in 7.5.37.6.4
Interim mitigation

Upgrade to FortiSOAR versions 7.6.4 or later (or latest available) which contain the patch for this vulnerability. Additionally, enforce network-level protections such as VPN usage and TLS inspection to make man-in-the-middle attacks more difficult.

Recommended fix High confidence

FortiSOAR 7.5.3 or later; FortiSOAR 7.6.4 or later (depending on your current major version)

  1. Identify the currently installed FortiSOAR version (7.5.x or 7.6.x)
  2. For FortiSOAR 7.5.x versions (7.5.0 to 7.5.2): Upgrade to version 7.5.3 or later
  3. For FortiSOAR 7.6.x versions (7.6.0 to 7.6.3): Upgrade to version 7.6.4 or later
  4. Before upgrading, take a full backup of the FortiSOAR database and configuration
  5. Schedule the upgrade during a maintenance window to minimize disruption
  6. Follow Fortinet's official upgrade documentation for your deployment type (PaaS or on-premise)
  7. After upgrade, verify the authentication mechanism is working correctly
  8. Confirm the new version is running: 7.5.3 or higher for 7.5 line; 7.6.4 or higher for 7.6 line
Caveat Standard FortiSOAR upgrade considerations apply - review release notes for any configuration or feature changes between your current version and the target version
