Leantime 3.6.2 and prior contains a broken access control vulnerability that allows authenticated users to read milestone data from projects they are not assigned to by supplying arbitrary integer milestone IDs to the tickets.getMilestone JSON-RPC endpoint. Attackers can enumerate integer milestone IDs through the JSON-RPC API to access project planning information, milestone titles, descriptions, and timelines across all projects on the instance regardless of project membership.
