CVE-2026-111606
Description
A flaw was found in Huly. A missing authorization vulnerability allows an authenticated remote attacker to merge arbitrary user profiles by invoking the mergeSpecifiedPersons remote procedure call (RPC). By supplying targeted user identifiers, an attacker can attach attacker-controlled credentials to a victim's profile and achieve account takeover.
Statement
This vulnerability is rated as Important due to the potential for complete account compromise across the network with low privileges and without requiring user interaction. While an authenticated actor with knowledge of target identifiers can hijack accounts by binding unauthorized credentials, Huly is not distributed or supported as part of any Red Hat product offerings.
