CVE-2026-48320

Estado: AnalizadaAlta (8.5)—

ColdFusion is affected by a reflected Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this vulnerability to inject malicious scripts into a web page, potentially gaining elevated access or control over the victim's account or session. 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.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N
