CVE-2024-34451: Ghost

Critical severity, CVSS 9.1. EPSS: 0.8% chance of exploitation in the next 30 days.

Ghost through 5.85.1 allows remote attackers to bypass an authentication rate-limit protection mechanism by using many X-Forwarded-For headers with different values. NOTE: the vendor's position is that Ghost should be installed with a reverse proxy that allows only trusted X-Forwarded-For headers.

Affected products

• Ghost Ghost: up to and including 5.85.1
