CVE-2022-26134
Atlassian Confluence Server/Data Center
Atlassian Confluence Server and Data Center contain a remote code execution vulnerability that allows for an unauthenticated attacker to perform remote code execution.
Exploitation status
- CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
- It is known to have been used in ransomware campaigns.
- US federal civilian agencies are required to remediate it by 2022-06-06. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.
Required action
