2) Infinite loop (CVE-ID: CVE-2020-16845)

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

The vulnerability exists due to infinite loop in "ReadUvarint" and "ReadVarint" in "encoding/binary". A remote attacker can consume all available system resources and cause denial of service conditions.


3) XML External Entity injection (CVE-ID: CVE-2021-21642)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient validation of user-supplied XML input. A remote authenticated attacker can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.

The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.


6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2021-21645)

The vulnerability allows a remote attacker to gain access to sensitive information on the system..

The vulnerability exists due to the affected plugin does not perform permission checks in several HTTP endpoints. A remote authenticated attacker can enumerate configuration file IDs.
