Potential share collision for recipients when caching is enabled in nextcloud server

Published Mar 30, 2023 · Updated Feb 11, 2025 · Assigned by GitHub_M

Description

Nextcloud server is an open source home cloud implementation. In affected versions when a recipient receives 2 shares with the same name, while a memory cache is configured, the second share will replace the first one instead of being renamed to `{name} (2)`. It is recommended that the Nextcloud Server is upgraded to 25.0.3 or 24.0.9. Users unable to upgrade should avoid sharing 2 folders with the same name to the same user.
