Password hash disclosure via complete User serialization
Published Sep 21, 2026 · Updated Sep 21, 2026
Sensitive information exposure in jishenghua jshERP 3.6 and earlier allows remote authenticated users to retrieve password hashes. The /user/info handler accepts an arbitrary user ID, loads the complete User object, and serializes it without clearing the password field, unlike /user/getUserSession. Any tenant account can obtain unsalted MD5 digests for other users in the same tenant, enabling offline password cracking.
