Cross Site Request Forgery (CSRF) vulnerability in old-peanut Open-Shop (aka old-peanut/wechat_applet__open_source) thru 1.0.0 allows attackers to gain sensitive information via crafted HTTP Post message.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
