The issue is related to Cross Site Request Forgery (CSRF) because randomly generated tokens are too easily guessable.

The account associated with a web services token is vulnerable to being exploited and logged into, resulting in information disclosure and often escalation of privileges.

The issue affects authentication methods that do not utilize Mahara's built-in login form, allowing users to log in even if their institution has been expired or suspended.

The issue allows profile pictures to be accessed without any access control checks, consequently allowing any of a user's uploaded profile pictures to be viewable by anyone, whether or not they were currently selected as the "default" or used in any pages.

The issue allows group members to lose access to the group files they uploaded if another group member changes the access permissions on them.

The issue allows plain text passwords to be recorded in the event log table during the user creation process if full event logging was turned on.

The issue allows logged-in users to remain logged in even after the institution they belong to has been suspended.

The issue allows a user to submit potentially dangerous payloads, such as XSS code, to be saved as their first name, last name, or display name in the profile fields. This can cause issues including escalation of privileges or unknown execution of malicious code when replying to messages in Mahara.

An issue allows unauthorized access to a user's account if the browser is closed without logging out of Mahara. The value in the `usr session` table remains, and an attacker can exploit this by adjusting the `mahara` cookie to the old value, thus gaining access to the user's account.
