In app/Controller/TagsController.php in MISP 2.4.118, users can bypass intended restrictions on tagging data.

MISP before 2.4.115 allows privilege escalation in certain situations. After updating to 2.4.115, escalation attempts are blocked by the __checkLoggedActions function with a "This could be an indication of an attempted privilege escalation on older vulnerable versions of MISP (<2.4.115)" message.

In app/webroot/js/event-graph.js in MISP 2.4.111, a stored XSS vulnerability exists in the event-graph view when a user toggles the event graph view. A malicious MISP event must be crafted in order to trigger the vulnerability.

app/Model/Server.php in MISP 2.4.109 allows remote command execution by a super administrator because the PHP file_exists function is used with user-controlled entries, and phar:// URLs trigger deserialization.

An issue was discovered in MISP 2.4.108. Organization admins could reset credentials for site admins (organization admins have the inherent ability to reset passwords for all of their organization's users). This, however, could be abused in a situation where the host organization of an instance creates organization admins. An organization admin could set a password manually for the site admin or simply use the API key of the site admin to impersonate them. The potential for abuse only occurs when the host organization creates lower-privilege organization admins instead of the usual site admins. Also, only organization admins of the same organization as the site admin could abuse this.
