CVE-2026-48277 is a critical Improper Input Validation vulnerability affecting Adobe ColdFusion versions 2025.9, 2023.20 and earlier. The flaw allows remote attackers to execute arbitrary code in the context of the current user without any user interaction, and the scope of impact is changed, indicating potential privilege or security boundary escalation. The vulnerability is classified under CWE-20 and has a CVSS v3.1 base score of 10.0, reflecting its high severity and ease of exploitation. No vendor advisory or patch information is currently available, and no known exploits in the wild have been reported as of the publication date.

Successful exploitation results in arbitrary code execution with the privileges of the current user, potentially leading to full system compromise depending on user rights. The vulnerability does not require user interaction and affects the security scope, increasing the risk of privilege escalation or broader impact within the affected environment.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, monitor Adobe's security advisories for updates. Apply standard security best practices to limit the privileges of ColdFusion service accounts and restrict network exposure to reduce attack surface.
