The MISP threat sharing platform is a free and open source software helping information sharing of threat and cyber security indicators.

Two cross-site scripting vulnerabilities have been discovered in MISP 2.4.68 and earlier versions. The vulnerability is caused by an error because MISP doesn't correctly process user input. On top of these XSS vulnerabilities, the MISP version was leaking to non authenticated users.
