Botiga Pro WordPress 插件在 1.6.5 版本之前，其某个 REST 路由未执行任何身份验证检查，使得未认证用户能够以任意值更新任意的 WordPress 选项，这可能导致权限提升和整个站点的接管。 同一路由还允许未认证用户存储任意的 Web 脚本，这些脚本随后会在站点前端的每个页面上执行，并且允许将任意文章移至回收站。

Vulnerability Title
Botiga Pro < 1.6.5 - Unauthenticated Arbitrary Blog Options Update via Templates Builder REST Route
Source: CVE Program / CVE List V5
Vulnerability Description
The Botiga Pro WordPress plugin before 1.6.5 does not perform any authorisation checks on one of its REST routes, allowing unauthenticated users to update arbitrary WordPress options with arbitrary values, which could lead to privilege escalation and a full site takeover. The same route also allows unauthenticated users to store arbitrary web scripts which are then executed on every page of the site's front end, as well as to move arbitrary posts to the trash.
