CVE-2026-48328
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 is affected by an Improper Input Validation vulnerability that could result in a Security feature bypass. A low-privileged attacker could leverage this vulnerability to bypass security measures and gain unauthorized read access. Exploitation of this issue does not require user interaction. 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 confidenceColdFusion contains an improper input validation vulnerability that allows a low-privileged attacker to bypass security measures and gain unauthorized read access. The scope change indicates the vulnerability impacts components beyond the vulnerable ColdFusion instance itself. No user interaction is required for exploitation.

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.
-
Identify installed ColdFusion versionCheck the ColdFusion administrator interface (typically at /cfide/administrator/) or inspect the version file in the installation directory. In ColdFusion Administrator, the version is displayed on the welcome page. Alternatively, check the installer log or registry for the exact version number.Affected if Version is either 2023 or 2025 (exact match to affected versions)
-
Confirm network exposure of ColdFusion instanceDetermine if the ColdFusion server is accessible from untrusted networks. Check firewall rules, reverse proxy configurations, and network ACLs that permit inbound HTTP/HTTPS traffic to the ColdFusion ports (default 8500, 8501, or standard web server ports).Affected if The ColdFusion instance is directly accessible from the internet or untrusted internal networks
-
Verify user input handling existsReview whether the ColdFusion application processes user-supplied input through URL parameters, form submissions, or API endpoints. Check for ColdFusion pages (CFM files) that accept and process request parameters without documented input validation.Affected if The ColdFusion instance processes untrusted user input through web-facing endpoints
-
Check for existing input validation controlsInspect application code for existing input validation, sanitization, or filtering mechanisms. Look for functions like HTMLEditFormat, HTMLCodeFormat, or custom validation logic in CFM templates and application.cfc/cfm files.Affected if No input validation exists or validation can be bypassed
An environment is affected if it runs ColdFusion 2023 or 2025, is network-accessible to untrusted users, and processes user-controlled input that could bypass security measures.

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 vendor-provided patches for ColdFusion and implement proper input validation and sanitization on all user-controlled input paths to prevent security feature bypass.
