Whilst we recommend upgrading to the latest fixed Confluence version, we have created a workaround for customers who are unable to immediately upgrade. Please see the below Workaround section
As part of this incident, we have observed that some third-party plugins may have compatibility issues with Confluence 10.2.16 and 10.2.17 (this fix version). Customers who rely on the below plugins should upgrade to Confluence 10.2.18, or use the workarounds detailed in the workarounds section until able to do so.
Impacted by CONFSERVER-104457: Search V2 public API uses unexported package com.atlassian.confluence.search.v2.aggregator, breaking third-party apps (Fixed)

Workaround
We have prepared a workaround for customers who are unable to immediately upgrade. To install them:
Shut down Confluence completely before proceeding.- Delete the below file corresponding to your respective Confluence version listed:
Confluence version Filename to be deleted 10.2.10 <confluence-install>/confluence/WEB-INF/atlassian-bundled-plugins/com.atlassian.confluence.plugins.confluence-editor-plugin-20.2.20.jar 10.2.11 <confluence-install>/confluence/WEB-INF/atlassian-bundled-plugins/com.atlassian.confluence.plugins.confluence-editor-plugin-20.2.23.jar 10.2.13 <confluence-install>/confluence/WEB-INF/atlassian-bundled-plugins/com.atlassian.confluence.plugins.confluence-editor-plugin-20.2.23.jar 10.2.14 <confluence-install>/confluence/WEB-INF/atlassian-bundled-plugins/com.atlassian.confluence.plugins.confluence-editor-plugin-20.2.38.jar 10.2.15 <confluence-install>/confluence/WEB-INF/atlassian-bundled-plugins/com.atlassian.confluence.plugins.confluence-editor-plugin-20.2.39.jar 10.2.16 <confluence-install>/confluence/WEB-INF/atlassian-bundled-plugins/com.atlassian.confluence.plugins.confluence-editor-plugin-20.2.42.jar - Download the patched JAR* from the links below for your respective Confluence version into <confluence-install>/confluence/WEB-INF/atlassian-bundled-plugins/:
Do not download or execute packages except from official Atlassian sources. Always check the source before downloading, and validate the download with the attached hashes
- Rename the file from confluence-editor-plugin-20.2.x.2.jar to com.atlassian.confluence.plugins.confluence-editor-plugin-20.2.x.2.jar
- Fix the file system permissions of the save file. It must match the permissions of the other existing files in this directory.
- Clear the Plugin Cache - Delete the contents of the following directories:
- <confluence-home>/plugins-cache/
- <confluence-home>/plugins-osgi-cache/
- <confluence-home>/bundled-plugins/
- <confluence-home>/plugins-temp/
- <confluence-install>/work
- Start Confluence.
We have seen reports that clearing the browser cache AND/OR CDN caches (if used) may be required in some cases, and we would recommend taking this step where possible.
