What is CVE-2026-124027?

ChatWiki, prior to version 2.10.0, exhibits a missing authentication flaw in the GET /manage/getLibRawFileOnePage route. This vulnerability permits unauthorized attackers to access documents belonging to different tenants, enabling the potential disclosure of sensitive information. By sequentially manipulating admin_user_id and file id parameters, an attacker can circumvent ownership checks, thereby retrieving PDF-rendered pages from any tenant's knowledge-base documents.
