Official description
Konga before 2.1.0 contains a privilege escalation vulnerability that allows low-privileged local attackers to execute arbitrary code by planting attacker-controlled OpenSSL configuration or library files in a hardcoded filesystem path absent from default installations. On Windows, the missing directory resides in a location writable by any authenticated local user, enabling attackers to create the directory and place malicious files that execute at the privilege level of the user or service account that launches Konga, facilitating privilege escalation.
