CVE-2026-27304
9.3Adobe · ColdFusion
Adobe ColdFusion is vulnerable to improper input validation, allowing unauthenticated attackers to execute arbitrary code.
Executive summary
Adobe ColdFusion is impacted by a critical input validation vulnerability that allows unauthenticated remote code execution.
Vulnerability
The application fails to properly validate input, leading to arbitrary code execution. This vulnerability is reachable by an unauthenticated attacker over the network (AV:A).
Business impact
Successful exploitation allows an attacker to execute arbitrary code with the privileges of the ColdFusion service. This level of access typically results in a complete compromise of the application, potential lateral movement within the network, and the loss of confidentiality and integrity for sensitive business data. Given the CVSS score of 9.3, this constitutes a critical security risk requiring immediate remediation.
Remediation
Immediate Action: Update Adobe ColdFusion to the version specified in the vendor security advisory (APSB26-38).
Proactive Monitoring: Monitor server access logs for unusual request patterns or attempts to execute system-level commands via the ColdFusion service.
Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block malicious input payloads targeting ColdFusion interfaces.
Exploitation status
Public Exploit Available: Unknown
Analyst recommendation
The high CVSS score of 9.3 reflects the severity of an arbitrary code execution flaw that does not require user interaction or authentication. Administrators should prioritize patching all instances of Adobe ColdFusion across the environment to the latest secure version immediately to eliminate this critical exposure.
