Technical Analysis
CVE-2026-111648 is an insecure direct object reference vulnerability in BuildAdmin through version 2.3.9. Authenticated backend administrators who possess the routine/adminInfo/edit permission can exploit this flaw by manipulating the id parameter to overwrite profile information of other administrators, including super administrators. The affected fields include avatar, nickname, email, mobile, and motto. This vulnerability arises from insufficient authorization checks on user-controlled keys within the administrative interface.
Potential Impact
An attacker with authenticated backend access and the routine/adminInfo/edit permission can modify profile details of other administrators, including super administrators. This could lead to unauthorized changes in contact information and profile data, potentially facilitating further social engineering or administrative abuse. However, the vulnerability does not allow privilege escalation beyond the attacker's existing permissions.
Mitigation Recommendations
No vendor advisory or patch information is provided. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict the routine/adminInfo/edit permission to trusted administrators only to minimize risk.
