description

Cronicle versions before 0.9.119 allow attacker-controlled account name data to be rendered in the administrator Activity Log without safe HTML encoding. An authenticated non-administrator can trigger script execution in an administrator's browser when that log is viewed; anonymous users may establish the same condition if self-registration is enabled.

mitigation

Upgrade Cronicle to version 0.9.119 or later. Until upgraded, disable self-registration and limit untrusted users' ability to modify account profile names.

fixed in 0.9.119
