CVE-2026-49344Network attack vector

Authenticated data disclosure via unguarded query execution

Published Jun 19, 2026 · Updated Jun 19, 2026

Information disclosure in Sourcentis Mercator before 2025.05.19 allows remote authenticated users to query restricted application data. QueryController::execute() accepts the Query Engine JSON DSL and resolves it as an Eloquent query without the authorization gate used by adjacent controller actions; hidden password hashes remain usable in LIKE filters. Any valid account, including the read-only Auditor role, can retrieve user-directory and out-of-scope CMDB records or infer a case-folded bcrypt hash, while the read-only engine cannot alter data or interrupt service.
