| Description: | | Atlassian Confluence is a widely deployed enterprise wiki and collaboration platform. CVE-2022-26134 is a critical, pre-authentication remote code execution flaw that stems from unsafe evaluation of OGNL (Object-Graph Navigation Language) expressions. Attackers can embed malicious OGNL in HTTP requests to reach the server-side expression interpreter, bypassing authentication and security controls. Successful exploitation grants the adversary full control of the Confluence host, enabling arbitrary command execution, lateral movement, deployment of ransomware, data exfiltration, or persistent backdoor installation. Because Confluence often integrates with corporate identity systems and stores sensitive project data, compromise frequently escalates to domain-level access and exposes intellectual property, customer records, and internal documentation. |
