1) Resource exhaustion (CVE-ID: CVE-2024-54677)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the examples web application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

2) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-50379)

The vulnerability allows a remote attacker to compromise the affected system.
