GHSA-c9v7-wmwj-vf6x: Withdrawn Advisory: SFTP is possible on the Proxy server for any user with SFTP access

January 3, 2024 (updated September 6, 2024)

An attacker that has access to nodes within the cluster may be able to SFTP to the Proxy Service. The user’s permissions on the Proxy server are still respected, so files can only be read or modified on the Proxy if the user has system access to read or write to them.
