DescriptionCVE.org

ColdFusion is affected by an Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection') vulnerability that could result in arbitrary code execution in the context of the current user. A low-privileged attacker could exploit this vulnerability to execute arbitrary code. Exploitation of this issue does not require user interaction. Scope is changed.

AnalysisAI

Remote code execution in Adobe ColdFusion 2023 (update ≤23) and ColdFusion 2025 (update ≤12) allows a low-privileged, authenticated attacker to inject directives into dynamically evaluated code (CWE-95, 'Eval Injection') and execute arbitrary code in the context of the current user without any user interaction. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:C, 9.9) reflects a network-reachable, low-complexity flaw with a scope change, meaning code executes beyond the initially authorized security context. …

Vulnerability AssessmentAI

Exploitation Exploitation requires network access to an affected ColdFusion 2023 (≤Update 23) or ColdFusion 2025 (≤Update 12) instance and low-privilege authenticated access to the application (CVSS PR:L) - a fully anonymous attacker is not indicated by the vector. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuine high-priority issue rather than an inflated CVSS score. … 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 Adobe-released update referenced in security bulletin APSB26-119 (https://helpx.adobe.com/security/products/coldfusion/apsb26-119.html); upgrade ColdFusion 2025 beyond Update 12 and ColdFusion 2023 beyond Update 23 to the fixed builds listed in that advisory (the input does not name an exact fixed build number, so confirm the precise version in the bulletin before deploying). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory all Adobe ColdFusion 2023 instances running update 23 or earlier and ColdFusion 2025 instances running update 12 or earlier, documenting network exposure and data sensitivity for each system. …
