# CVE-2026-82039

> 8.7 HIGH · 🧪 PoC

## Beschreibung

UTMStack before 11.2.16 contains a SQL injection vulnerability in UtmAssetGroupService.searchQueryBuilder() that allows authenticated attackers to inject arbitrary SQL by supplying malicious assetType and groupName values that are inserted unsanitized into a native PostgreSQL query via String.format(). Attackers can exploit the GET /api/utm-asset-groups/searchGroupsByFilter endpoint to execute arbitrary SQL with DBA privileges, enabling full database read, data modification, and potential filesystem access.
