An improper restriction of excessive authentication attempts vulnerability [CWE-307] in FortiTester Telnet port 2.3.0 through 3.9.1, 4.0.0 through 4.2.0, 7.0.0 through 7.1.0 may allow an unauthenticated attacker to guess the credentials of an admin user via a brute force attack.

Zammad 5.2.0 is vulnerable to privilege escalation. Zammad has a prevention against brute-force attacks trying to guess login credentials. After a configurable amount of attempts, users are invalidated and logins prevented. An attacker might work around this prevention, enabling them to send more than the configured amount of requests before the user invalidation takes place.

BookWyrm is a social network for tracking reading. Versions prior to 0.4.5 were found to lack rate limiting on authentication views which allows brute-force attacks. This issue has been patched in version 0.4.5. Admins with existing instances will need to update their `nginx.conf` file that was created when the instance was set up. Users are advised advised to upgrade. Users unable to upgrade may update their nginx.conf files with the changes manually.
