CyberRota Analysis
AI-GeneratedThe vulnerability in Cloudreve allows an attacker to exploit the WOPI PUT_RELATIVE handler, which improperly processes the X-WOPI-SuggestedTarget as a path, enabling unauthorized file creation or overwriting in unintended directories within the same owner account. This can lead to data manipulation and potential data loss. Users of versions prior to 4.17.0 should prioritize upgrading to the latest version to mitigate this risk.

Original NVD Description
Cloudreve is a self-hosted file management and sharing system. Prior to 4.17.0, the WOPI PUT_RELATIVE handler passes X-WOPI-SuggestedTarget to URI.JoinRaw as a path rather than a filename, allowing slash and dot-dot segments to escape the source file directory and create or conditionally overwrite files elsewhere in the same owner account. This issue is fixed in version 4.17.0.
