A moderate security vulnerability has been identified in Uptime Kuma platform that poses a significant threat to the confidentiality and integrity of user accounts.
When a user changes their login password in Uptime Kuma, a previously logged-in user retains access without being logged out.
This behaviour persists consistently, even after system restarts or browser restarts.
This vulnerability allows unauthorized access to user accounts, compromising the security of sensitive information.
The same vulnerability was partially fixed in https://github.com/louislam/uptime-kuma/security/advisories/GHSA-g9v2-wqcj-j99g but logging existing users out of their accounts was forgotten.
The impact of this vulnerability is moderate, as it enables attackers or unauthorized individuals to maintain access to user accounts even after the account password has been changed. This can lead to unauthorized data access, manipulation, or compromise of user accounts, posing a threat to the integrity and confidentiality of Uptime Kuma.
A better impact-analysis is included in https://github.com/louislam/uptime-kuma/security/advisories/GHSA-g9v2-wqcj-j99g
To mitigate the risks associated with this vulnerability, we made the server emit a refresh
event (clients handle this by reloading) and then disconnecting all clients except the one initiating the password change.
It is recommended to Update Uptime Kuma to >= 1.23.9
.
