Description Dhananjay Arunesh 2023-04-03 07:03:00 UTC
Nextcloud server is an open source home cloud implementation. In affected versions users that should not be able to download a file can still download an older version and use that for uncontrolled distribution. This issue has been addressed in versions 24.0.10 and 25.0.4. Users are advised to upgrade. There are no known workarounds for this vulnerability.
