Security Bulletin 11/2025 investigating

Incident Report for Communardo Service Center

Resolved

Dear customers,

after a thorough analysis, we recommend installing a minor update to the affected systems Confluence & Bitbucket and consider the update for Jira to be optional. We assessed the risk for Confluence as "medium" and for Bitbucket as "medium to high" for 9.4 versions & "high" for 8.19 versions. The fixed versions of Confluence & Jira were released in August & September and have already been applied to many systems.

Note: This is our general assessment and you should evaluate its applicability to your own IT environment. We only investigate/evaluate actively maintained LTS releases (except for Crowd & Fisheye/Crucible). If you are using a non-LTS release, please check additionally for your version or contact us via our Service Center.

You can find all the information regarding the fixed versions for your system in the post: https://confluence.atlassian.com/security/security-bulletin-november-18-2025-1671463469.html

If we are hosting your systems or proactively update your applications, we will directly communicate any information via the opened tickets (which have been created in the meantime) in our service center.

In case you have additional questions, please open a request in our Communardo Service Center:

Best regards,
Your Communardo Team
