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
ColdFusion versions 2023.18, 2025.6 and earlier are affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could result in a Security feature bypass. An attacker could leverage this vulnerability to access unauthorized files or directories outside the intended restrictions. Exploitation of this issue does not require user interaction.

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

ColdFusion versions 2023.18, 2025.6 and earlier contain a path traversal vulnerability allowing attackers to bypass security restrictions and access unauthorized files or directories outside the intended web root boundaries. The vulnerability is exploitable without any user interaction, making it particularly dangerous.

MitigationApply the vendor-supplied patches for ColdFusion 2023 and 2025 to address the path traversal vulnerability. Restrict file system access permissions as a defense-in-depth measure until patching is completed.

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 installed ColdFusion version
    Access the ColdFusion Administrator console and navigate to the System Information or Settings page to view the installed version number. Alternatively, check the version info in the ColdFusion installation directory or via command line if available.
    Affected if The installed version is 2023.18 or earlier, or 2025.6 or earlier.
  2. Confirm ColdFusion edition and build
    Verify the specific build number of ColdFusion if visible in the System Information page, as minor updates within the same major version may contain different patch levels.
    Affected if The build number corresponds to an unpatched release prior to the vendor fix.
  3. Verify directory restriction configuration
    Check if any directory restriction or file access controls are configured in ColdFusion Administrator under Security settings (RESTful Services, Access Protection, or similar).
    Affected if Directory restrictions are in place, as the vulnerability specifically allows bypassing these restrictions to access unauthorized files.
  4. Review access logs for anomalous file access patterns
    Examine ColdFusion server logs and web server access logs for unusual file read requests outside expected directories, particularly looking for patterns involving directory traversal sequences (e.g., ../../).
    Affected if Unusual traversal-style file access attempts are observed in logs, indicating potential exploitation attempts.

A user is affected if their ColdFusion installation is version 2023.18 or earlier, or 2025.6 or earlier, and directory restrictions are configured.

Mitigation

Apply the vendor-supplied patches for ColdFusion 2023 and 2025 to address the path traversal vulnerability. Restrict file system access permissions as a defense-in-depth measure until patching is completed.

Recommended fix High confidence

ColdFusion 2023.19+ or ColdFusion 2025.7+ (or latest available versions)

  1. Log in to the Adobe ColdFusion administrator console
  2. Navigate to the Updates section in the ColdFusion Administrator
  3. Check for available updates and install the latest ColdFusion update
  4. Alternatively, download the latest ColdFusion update from helpx.adobe.com and apply manually
  5. Restart the ColdFusion server after applying the update
  6. Verify the update was successful by checking the ColdFusion version in the Administrator
Caveat Standard ColdFusion update; review Adobe's update notes for any configuration or compatibility considerations
