What is Confluence and why is it significant from a cybersecurity perspective?

Confluence is a professional enterprise knowledge management and collaboration software used to build enterprise wikis. From a cybersecurity perspective, it is significant due to vulnerabilities like CVE-2021-26084, a Confluence Server Webwork OGNL injection that can allow attackers to exploit the platform. Understanding Confluence's environment, such as its database and user configuration, is crucial for both securing deployments and researching vulnerabilities, similar to analyzing flaws in other enterprise tools like Password Manager Pro or F5 BIG-IP.
