Improper Authentication

Mattermost is vulnerable to Improper Authentication. The vulnerability is caused by the use of constant-time comparison for remote cluster tokens, possibly allowing an attacker to retrieve the token during comparison due to the timing discrepancy...

CVE-2024-39830

Mattermost versions 9.8.x = 9.8.0, 9.7.x = 9.7.4, 9.6.x = 9.6.2 and 9.5.x = 9.5.5, when shared channels are enabled, fail to use constant time comparison for remote cluster tokens which allows an attacker to retrieve the remote cluster token via a timing attack during remote cluster token...
