Name of the Vulnerable Software and Affected Versions MyBB version 1.8.19

Description The issue allows remote attackers to obtain sensitive information. This occurs because the software discloses the username when it receives a password-reset request that lacks the code parameter.

Recommendations For MyBB version 1.8.19, consider restricting access to the password-reset functionality until a patch is available. As a temporary workaround, avoid using the password-reset feature without properly validating the code parameter.
