High

Base vector

AC:H/AV:N/A:H/C:H/I:H/PR:L/S:C/UI:N

Name of the Vulnerable Software and Affected Versions Gardener versions prior to 0.20.0

Description The issue allows information disclosure due to incorrect access control in seed clusters. This can be exploited by sending HTTP GET requests from one's own shoot clusters to foreign shoot clusters, as traffic from shoot to seed via the VPN endpoint is not blocked.

Recommendations For versions prior to 0.20.0, update to version 0.20.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the VPN endpoint to minimize the risk of exploitation.
