Mattermost versions 9.11.x <= 9.11.6, 10.4.x <= 10.4.1 fail to invalidate all active sessions when converting a user to a bot, with allows the converted user to escalate their privileges depending on the permissions granted to the bot.

Weakness

Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions.

Extended Description

Such a scenario is commonly observed when:

In the generic exploit of session fixation vulnerabilities, an attacker creates a new session on a web application and records the associated session identifier. The attacker then causes the victim to associate, and possibly authenticate, against the server using that session identifier, giving the attacker access to the user’s account through the active session.
