| タイトル | REBUILD 4.4.7-release Improper Authorization |
|---|
| 説明 | During the security review of "REBUILD", I discovered an unauthenticated server-side request forgery and arbitrary file write vulnerability in the "/commons/file-editor-save" endpoint. This vulnerability stems from the endpoint accepting a token exposed by a public share page, downloading content from an attacker-controlled "url", and writing the downloaded response to a data-directory path derived from the attacker-controlled "fileKey" without adequate callback authentication, URL restrictions, file ownership validation, or destination-path authorization. Therefore, attackers with access to a valid public share link can cause the server to fetch an arbitrary HTTP(S) resource and create or overwrite a selected relative file path in the REBUILD data directory. Immediate remedial measures are needed to ensure system security and protect data integrity.
