## Technical details

A user enumeration vulnerability exists in Frappe Framework's reset_password endpoint due to an observable discrepancy (CWE-203). Prior to the fix, the application returned different responses or confirmation messages depending on whether the submitted email address existed in the database. An unauthenticated remote attacker could exploit this by submitting a list of email addresses and observing the responses to identify valid accounts. The fix ensures that the application returns a consistent confirmation message regardless of whether the email address is registered. This has been patched in versions 15.106.0 and 16.16.0.
