CVE-2026-27306 is an improper input validation vulnerability in Adobe ColdFusion affecting versions 2023.18, 2025.6, and earlier. This flaw could enable an attacker with elevated privileges to execute arbitrary code in the context of the current user. Exploitation requires user interaction, namely opening a malicious file. The vulnerability is rated high severity with a CVSS 3.1 score of 8.4 (Attack Vector: Adjacent, Attack Complexity: Low, Privileges Required: High, User Interaction: None, Scope: Changed, Confidentiality/Integrity/Availability: High). No patch or official remediation level has been published by Adobe as of the data provided.

Successful exploitation could lead to arbitrary code execution with the privileges of the current user, potentially compromising confidentiality, integrity, and availability of the affected system. However, exploitation requires elevated privileges and user interaction, limiting the attack vector. There are no known active exploits in the wild.

Patch status is not yet confirmed — check the Adobe vendor advisory for current remediation guidance. Until an official fix is released, limit exposure by restricting elevated privileges and exercising caution with files received from untrusted sources.
