CVE-2026-3185Public exploitNetwork attack vector

Cross-user message disclosure via missing ownership check

Published Feb 25, 2026 · Updated Feb 25, 2026

Authorization bypass in feiyuchuixue sz-boot-parent 1.3.2-beta allows remote attackers to read other users' messages. The /api/admin/sys-message/{messageId} endpoint accepts an attacker-selected messageId and returns the referenced message without verifying that it belongs to the requester. Network access to the API is sufficient under the published no-privileges-required assessment; the demonstrated consequence is cross-user message disclosure only.
