Jenkins Tuleap Authentication Plugin non-constant time token comparison
Jenkins Tuleap Authentication Plugin 1.1.20 and earlier does not use a constant-time comparison when checking whether two authentication tokens are equal.
This could potentially allow attackers to use statistical methods to obtain a valid authentication token.
Tuleap Authentication Plugin 1.1.21 uses a constant-time comparison when validating authentication tokens.
