# CVE-2026-124027: ChatWiki before 2.10.0 Unauthenticated Document Disclosure via getLibRawFileOnePage

Status: published. Published: 2026-11-06. Updated: 2026-11-09.

ChatWiki before 2.10.0 contains a missing authentication vulnerability in the GET /manage/getLibRawFileOnePage route that allows unauthenticated attackers to read other tenants' documents. Attackers can enumerate sequential admin_user_id and file id query parameters, bypassing the ownership check, to retrieve PDF-rendered pages of any tenant's knowledge-base documents.
