Description

Mattermost versions 10.10.x <= 10.10.1, 10.5.x <= 10.5.9, 10.9.x <= 10.9.4 fail to validate the redirect_to parameter, allowing an attacker to craft a malicious link that, once a user authenticates with their SAML provider, could post the user’s cookies to an attacker-controlled URL.

Affected configurations

• mattermost mattermost server (>= 10.5.0 < 10.5.10) • mattermost mattermost server (>= 10.9.0 < 10.9.5) • mattermost mattermost server (>= 10.10.0 < 10.10.2)
