AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Network-reachable, unauthenticated OS command injection with no user interaction gives AV:N/AC:L/PR:N/UI:N, and code execution escaping to the host justifies S:C with full C/I/A impact.

2DescriptionCVE.org
ColdFusion is affected by an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could exploit this vulnerability to execute arbitrary code. Exploitation of this issue does not require user interaction. Scope is changed.
AnalysisAI
OS command injection in Adobe ColdFusion 2023 and 2025 enables remote, unauthenticated attackers to execute arbitrary operating-system commands in the context of the ColdFusion service account. Rated CVSS 10.0 with a scope change (S:C), this flaw stems from improper neutralization of special elements passed into an OS command and requires no user interaction. …

Vulnerability AssessmentAI
| Exploitation | No special conditions - remote unauthenticated exploitation against network-reachable Adobe ColdFusion 2023 and 2025 instances, per the CVSS vector AV:N/AC:L/PR:N/UI:N and the description's statement that exploitation does not require user interaction. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a top-priority vulnerability with essentially every risk signal maximized: the CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H yields a perfect 10.0, indicating network-reachable, low-complexity, unauthenticated exploitation with full confidentiality, integrity, and availability impact and a scope change onto the host. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the fixes described in Adobe security bulletin APSB26-90 (https://helpx.adobe.com/security/products/coldfusion/apsb26-90.html) for both ColdFusion 2023 and ColdFusion 2025; the input data does not specify an exact fixed build number, so consult the advisory for the precise patched version and install it promptly (Patch available per vendor advisory). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Conduct comprehensive inventory of all systems running Adobe ColdFusion 2023 or 2025; immediately restrict network access to ColdFusion instances to essential systems only; enable enhanced logging and alerting on ColdFusion process execution. …
