DescriptionCVE.org

ColdFusion versions 2023.18, 2025.6 and earlier are affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue does not require user interaction.

AnalysisAI

Remote code execution in Adobe ColdFusion 2023.18, 2025.6 and earlier allows unauthenticated adjacent network attackers to execute arbitrary code via improper input validation. The vulnerability requires no user interaction and achieves scope change, enabling attackers to break out of security boundaries. …

Vulnerability AssessmentAI

Exploitation Attacker must be on the same local network segment (AV:A). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This vulnerability presents significant real-world risk despite the adjacent network attack vector limitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker on the same corporate network segment as a ColdFusion application server (such as an employee with compromised credentials or a contractor on guest WiFi with LAN access) crafts malicious input containing code injection payloads and sends it to a vulnerable ColdFusion endpoint. Due to improper input validation, the server processes the malicious input without sanitization, executing the attacker's code in the ColdFusion application context. …
Remediation Apply the security updates referenced in Adobe Security Bulletin APSB26-38 immediately. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Identify and inventory all ColdFusion 2023.18, 2025.6, and earlier deployments in your environment; isolate affected systems from production networks if possible and restrict network access to ColdFusion ports to trusted sources only. …
