CVE-2026-27304 is an improper input validation vulnerability affecting Adobe ColdFusion versions 2023.18, 2025.6, and earlier. The flaw allows remote attackers to execute arbitrary code in the context of the current user without requiring user interaction. The vulnerability has a CVSS v3.1 base score of 9.3, reflecting its critical severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The vulnerability impacts confidentiality and integrity but not availability. No patch or official remediation level has been disclosed by Adobe as of the publication date.

Successful exploitation could lead to arbitrary code execution with the privileges of the ColdFusion process user, potentially compromising system confidentiality and integrity. Since no user interaction is required and the attack vector is remote, this vulnerability poses a significant risk to affected systems. There are no known exploits in the wild currently.
