What You Need to Do

Atlassian recommends that you upgrade to the latest Long Term Support release. For a full description of the latest version, see the Confluence Server and Data Center Release Notes. You can download the latest version from the download centre.

Note: If you run Confluence in a cluster, you will not be able to upgrade to the fixed versions without downtime, also known as a rolling upgrade. Follow the steps in Upgrading Confluence Data Center.

Mitigation

If you are unable to upgrade Confluence immediately, then as a temporary workaround, you can mitigate the CVE-2022-26134 issue by updating the following files for the specific version of the product.

For Confluence 7.15.0 - 7.18.0

If you run Confluence in a cluster, you will need to repeat this process on each node. You don't need to shut down the whole cluster to apply this mitigation.

Shut down Confluence.
Download the following 1 file to the Confluence server:
- xwork-1.0.3-atlassian-10.jar
Delete (or move the following JAR outside of the Confluence install directory):
```
<confluence-install>/confluence/WEB-INF/lib/xwork-1.0.3-atlassian-8.jar
```
Do not leave a copy of this old JAR in the directory.
Copy the downloaded xwork-1.0.3-atlassian-10.jar into <confluence-install>/confluence/WEB-INF/lib/
Check the permissions and ownership on the new xwork-1.0.3-atlassian-10.jar file matches the existing files in the same directory.
Start Confluence.

Remember, If you run Confluence in a cluster, make sure you apply the above update on all of your nodes.

For Confluence 6.0.0 - Confluence 7.14.2

If you run Confluence in a cluster, you will need to repeat this process on each node. You don't need to shut down the whole cluster to apply this mitigation.

Shut down Confluence.
Download the following 3 files to the Confluence server:

Delete (or move the following JARs outside of the Confluence install directory):

<confluence-install>/confluence/WEB-INF/lib/xwork-1.0.3.6.jar
<confluence-install>/confluence/WEB-INF/lib/webwork-2.1.5-atlassian-3.jar

Do not leave a copy of the old JARs in the directory.

Copy the downloaded xwork-1.0.3-atlassian-10.jar into <confluence-install>/confluence/WEB-INF/lib/
Copy the downloaded webwork-2.1.5-atlassian-4.jar into <confluence-install>/confluence/WEB-INF/lib/
Check the permissions and ownership on both new files matches the existing files in the same directory.
Change to directory <confluence-install>/confluence/WEB-INF/classes/com/atlassian/confluence/setup
1. Create a new directory called webwork
2. Copy CachedConfigurationProvider.class into <confluence-install>/confluence/WEB-INF/classes/com/atlassian/confluence/setup/webwork
3. Ensure the permissions and ownership are correct for:
```
<confluence-install>/confluence/WEB-INF/classes/com/atlassian/confluence/setup/webwork
```
```
<confluence-install>/confluence/WEB-INF/classes/com/atlassian/confluence/setup/webwork/CachedConfigurationProvider.class
```
Start Confluence.

Remember, If you run Confluence in a cluster, make sure you apply the above update on all of your nodes.
