Workaround

Due to the severity of this and a related issue, we've release a custom JAR file that includes a fix.

To implement it, please

1. Download the new file from https://packages.atlassian.com/maven-external/com/atlassian/confluence/plugins/confluence-jira-plugin/11.5.10/
   Please be careful when installing JAR files from the internet as they are executable code. In this case the JAR file is hosted on a known Atlassian domain, but we generally recommend against doing this
2. In Confluence, click the Cog icon on the top right, and click Manage Apps
3. On the Manage Apps page, click Upload App
4. Select the downloaded JAR file, and click Upload
5. Wait for the installation to complete
6. Perform a rolling restart on the cluster (restarting one node, waiting for it to come back up, restarting the next node)
   This is required to fix an issue with a misconfigured cache

Should you need to uninstall the app for any reason, please refer to Installing, Uninstalling, Upgrading and Downgrading Marketplace Apps on Confluence using REST API

Notes

The issue was not present on Confluence DC 7.13.9
