The provided commit diff and vulnerability description show a mismatch. The vulnerability describes an app creation limit bypass (business logic error), but the patched commit focuses on password length validation in User.java and ValidationUtils.java. There is no visible code modification related to app creation limits in the provided diffs. To identify vulnerable functions related to app limit enforcement, we would need to see the pre-patch code handling app creation quotas, which is not present in the provided commit data. The connection between the password-related patch and the described app limit vulnerability is unclear from the available information.
