Lower severity and a low EPSS score (0.14%). Track it; it rarely justifies an emergency change on its own.

Description

Kimai before 2.63.0 contains an improper authorization vulnerability in team access endpoints that allows authenticated users with team edit permissions and read-only access to grant team access to customers, projects, or activities. Attackers can exploit insufficient permission checks by sending POST requests to team access endpoints to modify access control lists for entities they should not be able to modify.
