Atlassian has published security advisories for four critical remote code execution vulnerabilities impacting Confluence, Jira, and Bitbucket servers, along with a companion app for macOS. All security issues addressed received a critical-severity score of at least 9.0 out of 10, based on Atlassian's internal assessment.

Due to the popularity of Atlassian products and their extensive deployment in corporate environments, system administrators should prioritize applying the available updates.

CVE-2022-1471: RCE in SnakeYAML library impacting multiple versions of Jira, Bitbucket, and Confluence products.

If administrators cannot apply the patch immediately, Atlassian recommends administrators to backup affected instances and take them offline.

If administrators are unable to apply the patch for CVE-2023-22524, the company recommends uninstalling the Atlassian Companion App.
