CVE-2023-22505Network attack vector

Authenticated remote code execution

Published Jul 18, 2023 · Updated Oct 1, 2024

Remote code execution in Atlassian Confluence Data Center and Server 8.0.0 through 8.3.1 allows remote authenticated users to execute code. Atlassian has not published the affected component, untrusted input, or faulty code operation, so the code-level mechanism remains undisclosed. A high-privileged Confluence account and network access are required; successful exploitation provides code execution in the server process context.
