The Koko Analytics plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 1.3.12. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

An information leak in kokoroe_members card Line 13.6.1 allows attackers to obtain the channel access token and send crafted messages.

Jumpserver is a popular open source bastion host, and Koko is a Jumpserver component that is the Go version of coco, refactoring coco's SSH/SFTP service and Web Terminal service. Prior to version 2.28.8, using illegal tokens to connect to a Kubernetes cluster through Koko can result in the execution of dangerous commands that may disrupt the Koko container environment and affect normal usage. The vulnerability has been fixed in v2.28.8.
