What is CVE-2026-87661?

Brocade Fabric OS versions prior to 9.2.2d and between 10.0.0 and 10.0.0a1 are susceptible to a Denial of Service vulnerability. This flaw allows an attacker to manipulate Apache configuration file data during the setup or re-initialization of services. By exploiting this vulnerability, an adversary can corrupt the configuration structure, leading to a scenario where the web management service fails to start or recover during system initialization. As a result, the administrative web interface can become persistently unavailable, hindering authorized access and management of the system.
