CVSS v3.1
Official Description
Open redirection vulnerability in the authentication system allows an attacker to use manipulated values in the X-Forwarded-Host header to alter the URLs generated by the application. A successful exploit could redirect authenticated users to malicious sites following login procedures or interaction with the interface, resulting in limited impact on confidentiality and integrity.
Technical Analysis
CVE-2026-10839 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (A) is needed, which slightly reduces the risk of mass automated attacks.
