CVE-2025-3026: Primekey Ejbca

Medium severity, CVSS 6.1. EPSS: 0.2% chance of exploitation in the next 30 days.

The vulnerability exists in the EJBCA service, version 8.0 Enterprise. Not tested in higher versions. By modifying the ‘Host’ header in an HTTP request, it is possible to manipulate the generated links and thus redirect the client to a different base URL. In this way, an attacker could insert his own server for the client to send HTTP requests, provided he succeeds in exploiting it.
