Description

A security vulnerability has been detected in jishenghua jshERP up to 3.6. This affects the function getUserByWeixinCode of the file jshERP-boot/src/main/java/com/jsh/erp/service/UserService.java of the component updatePlatformConfigByKey Endpoint. Such manipulation of the argument weixinUrl leads to server-side request forgery. The attack can be executed remotely. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.
