ColdFusion Code Execution Flaw: CVE-2026-27306 Requires Elevated Privileges
A critical Improper Input Validation vulnerability, identified as CVE-2026-27306, has been reported in Adobe ColdFusion. According to the National Vulnerability Database, this flaw affects ColdFusion versions 2023.18, 2025.6, and earlier, potentially leading to arbitrary code execution.
While the severity is rated HIGH with a CVSS score of 8.4, exploitation isn’t trivial. An attacker would first need elevated privileges on the system, and user interaction is a prerequisite; a victim must open a specially crafted malicious file for the exploit chain to complete. This isn’t your drive-by compromise, but it’s still a nasty bug if an adversary gets a foothold. The vulnerability is categorized under CWE-20, highlighting a classic input validation oversight.
