Cross-account data modification via unverified email ownership

Published Apr 4, 2025 · Updated Apr 4, 2025

Improper access control in Xujiangfei Admintwo 1.0 allows remote authenticated users to alter other users' account data via email. The /user/updateSet handler passes the supplied email to updateUserSetByEmail as the target identity without verifying that the current user owns that address. A valid session is required, and exploitation permits cross-account profile modification through a crafted POST request.
