Nextcloud Server is a data storage system for Nextcloud, a self-hosted productivity platform.

This allowed someone to send as many requests the server could handle in parallel to bruteforce protected details instead of the configured limit, default 8. Nextcloud Server versions 25.0.7 and 26.0.2 and Nextcloud Enterprise Server versions 21.0.9.12, 22.2.10.12, 23.0.12.7, 24.0.12.2, 25.0.7 and 26.0.2 contain patches for this issue. https://github.com/nextcloud/security-advisories/security/advisories/GHSA-qphh-6xh7-vffg https://github.com/nextcloud/server/pull/38274 https://hackerone.com/reports/1918525
