CVE-2026-75999: ColdFusion | Improper Input Validation (CWE-20)
ColdFusion is affected by an Improper Input Validation vulnerability that could result in arbitrary code execution in the context of the current user. A low-privileged attacker could exploit this vulnerability to execute arbitrary code. The vulnerable component is restricted to an administrative network zone by default. Exploitation of this issue requires user interaction in that a victim must open a malicious file. Scope is changed.
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Ensure the ColdFusion administrative network zone restriction remains in place (vulnerable component is restricted to an administrative network zone by default).
Event History
Frequently Asked Questions
Is a default ColdFusion deployment exposed to this vulnerability?
The vulnerable component is restricted to an administrative network zone by default. Exposure therefore depends on whether an attacker can reach that administrative zone or induce a user who can access it to open a malicious file.
What does an attacker need to exploit this issue?
The attacker needs low-level privileges and must cause a victim to open a malicious file. Successful exploitation can execute arbitrary code in the context of the current user.
What is the likely impact of successful exploitation?
Successful exploitation can result in arbitrary code execution and affects confidentiality, integrity, and availability. The vulnerability has changed scope, meaning its impact can extend beyond the initially affected security authority.
