Name of the Vulnerable Software and Affected Versions MyBB versions prior to 1.8.4

Description The issue affects the administrative backend, allowing remote authenticated users to inject arbitrary web script or HTML. This can be achieved through various fields in different modules, including the MIME-type field in the config-attachment types module, title or short description fields in the config-mycode or user-groups modules, and others. The estimated number of potentially affected devices worldwide is not specified. There is no information about real-world incidents where this issue was exploited.

Recommendations For versions prior to 1.8.4, update to version 1.8.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the administrative backend to minimize the risk of exploitation. Avoid using the vulnerable fields in the affected modules until the issue is resolved.
