Original advisory

Published

Kimai is an open-source time tracking application. Prior to 2.57.0, GET or POST requests to /en/admin/activity/create/{project} and /en/admin/project/create/{customer} require only the generic create_activity or create_project capability and do not verify edit access to the supplied Project or Customer object. A user who knows a valid project.id or customer identifier can use the preset-parent creation logic in src/Controller/ActivityController.php or src/Controller/ProjectController.php to persist a new child business object under an unauthorized parent, polluting project or customer configuration and influencing later time-entry, rate, reporting, and billing behavior. This issue is fixed in version 2.57.0.
