CVE-2026-111648 build-admin CVE debrief

BuildAdmin through 2.3.9 contains an insecure direct object reference vulnerability that allows authenticated backend administrators to modify other administrators' profiles via the id parameter in the routine/adminInfo/edit endpoint. This vulnerability enables attackers with the routine/adminInfo/edit permission to overwrite various fields, including avatar, nickname, email, mobile, and motto, potentially affecting super administrators' sensitive information. Defenders should assess exposure, prioritize verification for instances with multiple administrators, and monitor for suspicious activity.
