CVE-2025-30292
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 · uneditedColdFusion versions 2023.12, 2021.18, 2025.0 and earlier are affected by a reflected Cross-Site Scripting (XSS) vulnerability. If an attacker is able to convince a victim to visit a URL referencing a vulnerable page, malicious JavaScript content may be executed within the context of the victim's browser.
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 confidenceColdFusion versions 2023.12, 2021.18, 2025.0 and earlier contain a reflected XSS vulnerability where user-supplied input in a web parameter is improperly sanitized and reflected back in the HTTP response without proper encoding, allowing arbitrary JavaScript execution in victim browsers via maliciously crafted URLs.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify ColdFusion installed versionAccess the ColdFusion Administrator console (typically at /cfide/administrator/) and check the version displayed on the login or about page, or check the version file in the ColdFusion installation directoryAffected if The installed version is 2023.12 or earlier, 2021.18 or earlier, or 2025.0
-
Identify user input reflection pointsReview application code for CFML pages that accept URL or form parameters and reflect them back in the HTTP response (using parameters like id, name, returnurl, or similar) without using encodeForHTML or similar encoding functionsAffected if Any page reflects URL or form parameters in the response without output encoding
-
Test for XSS reflectionSubmit a test payload such as <script>alert('XSS')</script> or a benign alternative like <img src=x onerror=alert(1)> as a URL parameter to suspected pages and inspect the HTTP response to see if the payload is returned unencodedAffected if The submitted payload appears in the response without HTML encoding (e.g., tags are not converted to < and >)
-
Check HTTP response headersCapture HTTP responses from pages with reflected parameters and verify whether the Content-Type header includes proper charset (e.g., charset=UTF-8) and whether output encoding functions are being used server-sideAffected if Responses do not properly encode reflected user input or lack proper Content-Type configuration
A user is affected if they are running ColdFusion 2023.12 or earlier, 2021.18 or earlier, or 2025.0 AND have pages that reflect URL/form parameters without output encoding.

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.
dbcve · scopedApply Adobe's official patch for this vulnerability when released. In the interim, implement output encoding on all user input reflection points and deploy strict Content-Security-Policy headers to mitigate XSS execution.
ColdFusion 2021.19+ (or latest), ColdFusion 2023.13+ (or latest), or ColdFusion 2025.1+ (or latest)
- 1. Identify the currently installed ColdFusion version (2021, 2023, or 2025)
- 2. Navigate to the Adobe ColdFusion downloads page at helpx.adobe.com
- 3. Download the latest available update for your specific ColdFusion version
- 4. Apply the update following Adobe's standard installation procedures
- 5. Restart the ColdFusion server after applying the update
- 6. Verify the update was successful by checking the ColdFusion administrator console
