Description

Impact

An attacker may leverage a vulnerability in the password reset feature to capture a user's token and reset the password on their behalf.

The attacker must know the email address of a valid account on the site, and the actual user must blindly click the link in their email even though they didn't request the reset.

Patches

This has been fixed in 6.3.3 and 5.73.10.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
