Description
Mastodon is a free, open-source social network server based on ActivityPub. In Mastodon before 4.4.6, 4.3.14, and 4.2.27, when an administrator resets a user account's password via the command-line interface using `bin/tootctl accounts modify --reset-password`, active sessions and access tokens for that account are not revoked. This allows an attacker with access to a previously compromised session or token to continue using the account after the password has been reset. This issue has been patched in versions 4.2.27, 4.3.14, and 4.4.6. No known workarounds exist.

Executive Summary

This vulnerability occurs in Mastodon versions before 4.4.6, 4.3.14, and 4.2.27, where when an administrator resets a user's password via the command-line interface, the active sessions and access tokens for that user are not revoked. This means that an attacker who has access to a previously compromised session or token can continue to use the account even after the password has been reset.

Impact Analysis

The vulnerability allows an attacker with access to a previously compromised session or access token to maintain unauthorized access to a user's account even after the password has been reset by an administrator. This can lead to continued unauthorized use of the account, potentially compromising user data or actions performed under that account.

Mitigation Strategies

Upgrade Mastodon to version 4.4.6, 4.3.14, or 4.2.27 or later, where the issue has been patched. There are no known workarounds.
