概要

Apostrophe CMS versions between 2.63.0 to 3.3.1 affected by an insufficient session expiration vulnerability, which allows unauthenticated remote attackers to hijack recently logged-in users' sessions. As a mitigation for older releases the user account in question can be archived (3.x) or moved to the trash (2.x and earlier) which does disable the existing session.

NVD の説明

Apostrophe CMS versions prior to 3.3.1 did not invalidate existing login sessions when disabling a user account or changing the password, creating a situation in which a device compromised by a third party could not be locked out by those means. As a mitigation for older releases the user account in question can be archived (3.x) or moved to the trash (2.x and earlier) which does disable the existing session.
