CVE-2023-48305

Summary

CVE-2023-48305 is a vulnerability affecting Nextcloud Server, a data storage solution for the open-source cloud platform Nextcloud. Versions 25.0.0 through 27.1.0, including both Nextcloud Server and Nextcloud Enterprise Server, are impacted if the log level is set to debug. These versions log user passwords in plaintext in the log file, posing a serious security risk if the file is leaked or shared. Patched versions 25.0.11, 26.0.6, and 27.1.0 are available to address this issue. As a temporary solution, adjusting the `loglevel` config setting to 1 or higher (recommended to be higher than 1 in production environments) can prevent password logging.
