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
RackN Digital Rebar through 4.6.14, 4.7 through 4.7.22, 4.8 through 4.8.5, 4.9 through 4.9.12, and 4.10 through 4.10.8 has exposed a privileged token via a public API endpoint (Incorrect Access Control). The token can be used to escalate privileges within the Digital Rebar system and grant full administrative access.

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

RackN Digital Rebar contains an Incorrect Access Control vulnerability where a privileged authentication token is exposed via a publicly accessible API endpoint. This allows unauthenticated attackers to retrieve administrative credentials and gain full system access with full administrative privileges.

MitigationUpdate Digital Rebar to a version beyond 4.10.8 (or the appropriate patched version for your branch) to remediate the token exposure. Additionally, restrict network access to the API endpoint as an interim control until patching is complete.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Digital Rebar version
    Run 'rebar version' command or check the web UI system information page to determine the installed version
    Affected if Version is <= 4.6.14, OR between 4.7.0 and 4.7.22, OR between 4.8.0 and 4.8.5, OR between 4.9.0 and 4.9.12, OR between 4.10.0 and 4.10.8
  2. Verify API network exposure
    Review firewall rules, security groups, or network ACLs to check if the Digital Rebar API port is accessible from untrusted IP addresses or the public internet
    Affected if API port (typically 443 or 3000) is exposed to the internet or untrusted networks without IP restrictions
  3. Test for unauthenticated token retrieval
    Send an unauthenticated HTTP GET request to the API endpoint using a tool like curl or a browser, for example: curl -k https://<your-host>/api/v3/users/1
    Affected if Request returns privileged authentication tokens, admin credentials, or sensitive user data without requiring authentication

Environment is affected if running an affected version AND the API endpoint is network-accessible, allowing unauthenticated attackers to retrieve administrative tokens.

Upgrade available Upgrade to a release after 4.10.8
Interim mitigation

Update Digital Rebar to a version beyond 4.10.8 (or the appropriate patched version for your branch) to remediate the token exposure. Additionally, restrict network access to the API endpoint as an interim control until patching is complete.

Recommended fix Moderate confidence

Upgrade to 4.10.9 or later (latest stable 4.10.x release), or to the latest release in your current version branch (4.6.15+, 4.7.23+, 4.8.6+, or 4.9.13+)

  1. Identify the currently running Digital Rebar version using the UI or CLI
  2. Determine the appropriate upgrade path based on your current version branch (4.6.x, 4.7.x, 4.8.x, 4.9.x, or 4.10.x)
  3. Review the Digital Rebar upgrade documentation at docs.rackn.io for your version branch
  4. Back up the Digital Rebar platform configuration and data before upgrading
  5. Upgrade to the latest stable release in your version branch (4.6.15+, 4.7.23+, 4.8.6+, 4.9.13+, or 4.10.9+)
  6. Alternatively, upgrade to the latest 4.10.x stable release (4.10.9 or later) which contains the fix
  7. After upgrade, verify the fix by confirming the privileged token is no longer exposed via public API endpoints
  8. Rotate any tokens that may have been compromised during the vulnerability window
