An authenticated standard user could reset the password of other users (including the admin) by altering form data. Affects kanboard before 1.0.46.

Kanboard versions 1.2.48 and below is vulnerable to a critical authentication bypass when REVERSE_PROXY_AUTH is enabled. The application blindly trusts HTTP headers for user authentication without verifying the request originated from a trusted reverse proxy. An attacker can impersonate any user, including administrators, by simply sending a spoofed HTTP header. This issue is fixed in version 1.2.49.

A vulnerability in Kanboard up to version 1.2.52 (fixed in commit 564cc30) allows an authenticated user who is a member of at least one project to move (hide/corrupt) tasks from any other project, including private ones they have no access to. The issue is in the save() method of BoardAjaxController, which does not verify that the supplied task_id actually belongs to the attacker-supplied project_id.
