MISP 2.4.145 and 2.4.146 released

MISP 2.4.145 and 2.4.146 released including a massive update to the MISP warning-lists, various improvements and security fixes.

MISP warning-lists improvements.

Warning lists system has been significantly improved (thanks to Jakub Onderka).

  • Custom warning lists can be created and managed in the MISP user-interface
  • Warning lists can be now imported via the API
  • Warning lists changes are exported in the ZMQ channel
  • Warning lists include new categories to describe the scope

New features

Summary email notification

Email notifications have received a new configuration setting: New event summaries only. This feature publishes the normal alert reports excluding attributes and objects, thereby only describing a summary of the alert. This can be used when encryption cannot be enabled and organisations still require email alerting.


New documentation has been added to describe the session and cookie handling in MISP.


  • Thanks to a new feature, you can now create read only authentication keys (don’t forget to enable the advanced authentication key feature for this to work).

Security Fixes

Thanks to the reporters including Nicolas Vidal from TEHTRIS.

Various improvements

  • [OpenAPI] - Missing return formats added to the documentation
  • [server caching] only push data to redis / logs if there’s something to push
  • [attribute] validation tightened for empty strings. A value containing only control characters will now be blocked from entry.
  • [feeds] Added 3 daily feeds (ssh bruteforce, telnet bruteforce, URLs seen) from the APNIC Community Honeynet Project


We would like to thank all the contributors, reporters and users who have helped us in the past months to improve MISP and information sharing at large. This release includes multiple updates in misp-objects, misp-taxonomies and misp-galaxy .

As always, a detailed and complete changelog is available with all the fixes, changes and improvements.
