Description OSIDB Bzimport 2025-06-12 17:08:20 UTC 
A Denial of Service (DoS) vulnerability can be triggered by sending a single HTTP GET request with an extremely large X-Forwarded-For header to an HTTP endpoint. This results in server memory exhaustion, portentially leading to a crash or unresponsiveness. The attack does not require authentication, making it exploitable by any remote user.
