Atlassian warned its customers that multiple threat groups are exploiting a Confluence Server zero-day vulnerability in its servers.
Any unauthenticated attackers can target its Confluence Server and Data Center by a critical vulnerability that can be exploited for remote code execution.
The company advised its users have been advised to prevent access to their Confluence servers from the internet, or simply disable these instances, as all supported versions of Confluence Server and Data Center are affected.
However, Atlassian expects fixes to become available soon.
