      "title": "Reusable Account Activation and Recovery Tokens Allow Repeated Account Takeover in vulnerability-lookup",
      "summary": "Vulnerability-Lookup contains an \nauthentication weakness in its account activation and password-recovery \nmechanism. Activation and recovery links were generated using stateless \nsigned tokens containing only the user's login. Although the token \nsignature and age were validated, the application did not track whether a\n token had already been successfully used. As a result, a captured \nactivation or password-recovery link remained valid for the entire \nconfigured TOKEN_VALIDITY_PERIOD, even after the associated password had been changed. \n\n\nAn attacker who obtains a valid \nactivation or recovery token could therefore replay it multiple times \nduring its validity period to set a new password and repeatedly take \ncontrol of the affected account. In addition, tokens were not bound to a\n specific purpose, allowing the same token mechanism to be used across \nactivation and recovery workflows. The patch introduces purpose-bound \ntokens and a random nonce whose SHA-256 digest is stored with the user \naccount. The nonce is invalidated after a successful password change, \nmaking tokens single-use, while issuing a new token invalidates any \npreviously issued token.  The password-setting operation now explicitly consumes the token before committing the account change. \n\n\nSuccessful exploitation requires \nthe attacker to obtain a currently valid activation or recovery link, \nbut does not require knowledge of the victim's existing password or an \nauthenticated session.",
