What is CVE-2026-119648?

The Tencent BlueKing CMDB, specifically version 3.14.6, is vulnerable due to a missing authorization check that permits authenticated users to access the host details of other businesses. This flaw arises from improper handling of search requests in the endpoint /api/v3/hosts/search/asstdetail, where authorization checks are skipped. As a result, adversaries can exploit this weakness by crafting specific POST requests with tailored search conditions to expose sensitive host attributes and topology information, risking data confidentiality across business boundaries.

Affected Version(s)

bk-cmdb 0 <= 3.14.6
