CVE-2023-39961

Nextcloud Server provides data storage for Nextcloud, an open source cloud
platform. Starting in version 24.0.4 and prior to versions 25.0.9, 26.0.4, and
27.0.1, when a folder with images or an image was shared without download
permissions, the user could add the image inline into a text file and download
it. Nextcloud Server versions 25.0.9, 26.0.4, and 27.0.1 and Nextcloud
Enterprise Server versions 24.0.12.5, 25.0.9, 26.0.4, and 27.0.1 contain a patch
for this issue. No known workarounds are available.

All versions < 27 are end of life.
Version 28.0.4 os in devel and factory.
I have no rights for SLE.

So no more i can do.
