# MISP 2.4.137 released

We have released 2.4.137, a security and bug fix release including a collection of fixes and improvements collected over the past month.

Building tools for the security community sure has its perks - over the past week we have received two independent security test results of two separate organisations, revealing several vulnerabilities. The update to this version is therefore highly recommended.

A little note on vulnerability - we [always welcome organisations helping us secure MISP](https://www.misp-project.org/security/) and our tooling in general and would hereby like to thank everyone taking part in the process!

# Several vulnerabilities resolved

- [CVE-2021-25324] Stored XSS via the galaxy cluster view - Discovered by Daniel Kubica of ESET, spol. s r.o.
- [CVE-2021-25325] Stored XSS via the galaxy element index - Discovered by Daniel Kubica of ESET, spol. s r.o.
- [CVE-2021-25323] Weak default password change request policy not requiring the entry of the current password - Discovered by Daniel Kubica of ESET, spol. s r.o.
- [CVE-2021-3184] Reflected XSS via the set homepage button - Reported by an anonymous party

# A long list of quality of life improvements

- The synchronisation now compresses the data exchanged, improving the transfer rates during the exchange
- Additional metrics and comparison tools for the sync connections
- Better management of API key usage along with logging
- A new tool that allows the exclusion of certain values from the correlation engine (useful to avoid having regularly observed values recurring in a large number of events generating too much noise)

Along with many other fixes. A special thank you to @JakubOnderka for providing a steady stream of QoL improvements, making MISP more pleasant to use by the day!
