MISP 2.4.185 released with sighting performance improvements, security and bugs fixes

February 20, 2024

We are happy to announce the immediate availability of MISP 2.4.185. This is mainly a bug fix release resolving several issues as well as tightening the security posture of the org image handling.

Security fixes

We have moved the organisation images out of the webroot to avoid a rogue administrator from being able to upload a crafted, malicious organisation image and for unsuspecting users to be redirected to a malicious direct link of the image. Whilst this vulnerability is highly unlikely, requiring a compromised/rogue site administrator as a premise, the issue is valid and has been fixed.

Thanks to Yusuke Nakajima and Andrei Agape of Teliacompany for both delivering reports of this issue.


Various fixes affecting the API, proxy settings, sighting synchronisation. The synchronisation bug in particular could easily bring large, sighting rich instances (such as our own) to its knees when a remote instance tried to synchronise via a pull.

We would hereby like to again thank for our active community for supplying fixes, bug reports, vulnerability reports and suggestions for the continuous improvement of MISP, the tool definitely wouldn’t be what it is today without all your help!

Details changes are available in Changelog.
