Last modified
CVE-2021-25979 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 1.10% chance of exploitation in the next 30 days.
