What is CVE-2024-52521?

A vulnerability in Nextcloud Server reveals that the usage of MD5 hashes to verify the uniqueness of background jobs may lead to incorrect job handling. This could prevent some jobs from being queued properly, as they might be mistakenly recognized as duplicates. The issue is mitigated in newer versions by transitioning to SHA256 hashing, which significantly enhances the accuracy of job identification. Users are advised to upgrade their Nextcloud Server installations to version 28.0.10, 29.0.7, or 30.0.0 to avoid potential processing failures.
