Technical description

Nextcloud Server is the file server software for Nextcloud, a self-hosted productivity platform.

These long names are then loaded into memory on usage, resulting in impacted performance. Versions 22.2.7 and 23.0.4 contain a fix for this issue. There are currently no known workarounds available.
