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 2025.9, 2023.20 and earlier are affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could exploit this vulnerability to inject malicious scripts into a web page, potentially gaining elevated access or control over the victim's account or session. Exploitation of this issue requires user interaction in that a victim must open a malicious file. Scope is changed.

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

ColdFusion versions 2025.9 and earlier contain an Improper Input Validation vulnerability that allows attackers to inject malicious scripts into web pages. Exploitation requires a victim to open a malicious file, enabling arbitrary code execution in the context of the current user with potentially elevated privileges.

MitigationUpdate ColdFusion to the latest patched version provided by Adobe. Implement additional input validation and sanitization for file handling operations, and educate users about the risks of opening untrusted files.

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 Adobe ColdFusion is installed
    Check for ColdFusion installation directories (typically under C:\ColdFusion or /opt/coldfusion on Linux) or look for ColdFusion services running on the system
    Affected if ColdFusion is found to be installed on the system
  2. Determine the installed ColdFusion version
    Check the ColdFusion administrator interface (typically at /cfadmin) or look for version files in the installation directory. The version should match 2023 or 2025.x up to 2025.9
    Affected if The installed version is 2023 (any update) or 2025.x where x is 0 through 9 (2025.9 or earlier)
  3. Verify if file handling or import features are accessible
    Check the ColdFusion administrator settings for file upload, import, or file handling modules. These are typically found under Server Settings or Security settings in the CFAdmin interface
    Affected if File handling or import functionality is enabled and accessible to users
  4. Inspect for suspicious files in ColdFusion directories
    Look for unexpected .cfm, .cfc, or script files in the web root, /cfide, or temporary directories that may indicate exploitation attempts
    Affected if Unexpected or malicious files are found that were not intentionally deployed

If ColdFusion version 2023 or 2025 (up to 2025.9) is installed with file handling features exposed, the environment is vulnerable to this improper input validation flaw.

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

Update ColdFusion to the latest patched version provided by Adobe. Implement additional input validation and sanitization for file handling operations, and educate users about the risks of opening untrusted files.

Recommended fix Moderate confidence

ColdFusion 2023: upgrade to latest 2023 release (beyond version 2023.20); ColdFusion 2025: upgrade to latest 2025 release (beyond version 2025.9)

  1. 1. Identify your current ColdFusion installation version by checking the ColdFusion Administrator or the version information in the installation directory.
  2. 2. For ColdFusion 2023 users: Upgrade to a version higher than 2023.20 (the latest available 2023 release).
  3. 3. For ColdFusion 2025 users: Upgrade to a version higher than 2025.9 (the latest available 2025 release).
  4. 4. Download the updated ColdFusion installer from the official Adobe ColdFusion downloads page (https://www.adobe.com/products/coldfusion/download.html).
  5. 5. Before upgrading, perform a complete backup of your ColdFusion instance including the cfusion directory, databases, and any custom configurations.
  6. 6. Apply the upgrade following Adobe's standard upgrade documentation for your specific version.
  7. 7. After upgrade, verify that all custom applications and integrations function correctly.
  8. 8. Review and test any third-party ColdFusion packages or extensions that may have been installed.
Caveat Standard upgrade risks apply: review compatibility notes for your specific applications and ensure third-party plugins/extensions support the target version
