Summary
CVE-2023-38489 is a vulnerability affecting Kirby, a content management system. This issue, present in versions prior to 3.5.8.3, 3.6.6.3, 3.7.5.2, 3.8.4.1, and 3.9.6, poses a risk for sites with user accounts. The flaw is related to insufficient session expiration, enabling attackers to maintain unauthorized access even after a user changes their password. Kirby failed to invalidate user sessions with old passwords, leaving affected sites vulnerable. The vulnerability can be exploited when users share devices or browsers with potentially untrusted individuals or when attackers use previously stolen passwords. The latest releases, Kirby 3.5.8.3, 3.6.6.3, 3.7.5.2, 3.8.4.1, and 3.9.6, include a patch to address this issue by keeping track of the hashed password in each active session.
