Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Concrete CMS (concrete5 on Packagist) versions before 9.1.0 do not rate-limit password reset requests. The source does not describe the attacker's position or what an attacker could achieve beyond the missing limit. Upgrade concrete5/concrete5 to version 9.1.0 or later, which is listed as the fixed version.
