1) Missing Authorization (CVE-ID: N/A)

CWE-ID: CWE-862 - Missing Authorization

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to improper access control in the local_trusted authentication and hostname validation logic when handling requests from a DNS-rebound origin. A remote attacker can lure a victim into opening a crafted webpage to execute arbitrary code.

User interaction is required to open a malicious webpage, and exploitation is limited to instances running in the default local_trusted mode.
