## How to fix

- Fixed in Joplin Server 3.7.2

## Technical details

The vulnerability stems from token-purpose confusion: TokenModel.ts stores CSRF, account-confirmation, email-change, and password-reset tokens without recording their intended purpose, and UserModel.resetPassword accepts any token returned by TokenModel.userFromToken. An attacker with network access to the public password-reset endpoint can abuse tokens obtained through a separate disclosure to perform unauthorized password resets. The fix scopes tokens by purpose in a database schema migration.

## Affected products
