HIGH 8.8ColdFusion versions 2025.9, 2023.20 and earlier are affected by a reflected Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this vulnerability to inject malicious scripts into a web page, potentially resulting in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious link. Scope is changed.
Severe if exploited (CVSS 8.8), but no known exploitation and low modeled probability. Patch on a normal cadence.
