Description SMASH SMASH 2023-12-24 09:13:04 UTC 
Nextcloud Server provides data storage for Nextcloud, an open source cloud platform. In Nextcloud Server prior to versions 26.0.9 and 27.1.4; as well as Nextcloud Enterprise Server prior to versions 23.0.12.13, 24.0.12.9, 25.0.13.4, 26.0.9, and 27.1.4; when a (reverse) proxy is configured as trusted proxy the server could be tricked into reading a wrong remote address for an attacker, allowing them executing authentication attempts than intended. Nextcloud Server versions 26.0.9 and 27.1.4 and Nextcloud Enterprise Server versions 23.0.12.13, 24.0.12.9, 25.0.13.4, 26.0.9, and 27.1.4 contain a patch for this issue. No known workarounds are available.

Version 24 is End of Life since 2023-04.
Version 24.0.12 is the latest code. And 24.0.12.9 is only aviable for Enterprise.
And Leap 15.6 is not released at this time.
So, please push latest version 28 from factory to Leap 15.6.
