OneUptime is a solution for monitoring and managing online services. In version 9.0.5598, a low-permission user can create new accounts through a direct API request instead of being restricted to the intended interface. This issue has been patched in version 9.1.0.

OneUptime is a solution for monitoring and managing online services. Prior to version 8.0.5567, OneUptime is vulnerable to privilege escalation via Login Response Manipulation. During the login process, the server response included a parameter called isMasterAdmin. By intercepting and modifying this parameter value from false to true, it is possible to gain access to the admin dashboard interface. However, an attacker may be unable to view or interact with the data if they still do not have sufficient permissions. This issue has been patched in version 8.0.5567.

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 17.10 before 18.4.5, 18.5 before 18.5.3, and 18.6 before 18.6.1 that could have allowed an unauthenticated user to cause a Denial of Service condition by sending specifically crafted requests containing malicious JSON payloads.

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_event: call disconnect callback before deleting conn In hci_cs_disconnect, we do hci_conn_del even if disconnection failed. ISO, L2CAP and SCO connections refer to the hci_conn without hci_conn_get, so disconn_cfm must be called so they can clean up their conn, otherwise use-after-free occurs.

In the Linux kernel, the following vulnerability has been resolved: kernfs: fix use-after-free in __kernfs_remove Syzkaller managed to trigger concurrent calls to kernfs_remove_by_name_ns() for the same file resulting in a KASAN detected use-after-free. The race occurs when the root node is freed during kernfs_drain(). To prevent this acquire an additional reference for the root of the tree that is removed before calling __kernfs_remove().
