Atlassian

Atlassian discovered a vulnerability in its Confluence Server which they need to patch to remedy a Critical-rated flaw.

Confluence Server Webwork OGNL injection vulnerability could allow an authenticated user, or unauthenticated user, to execute arbitrary code on a Confluence Server or Data Center instance.

However, Atlassian's own Confluence Cloud was patched but other hosted Confluence offerings might be vulnerable.
