FlatPress CMS version latest is vulnerable to Cross-Site Request Forgery (CSRF) attacks that allow an attacker to enable or disable plugins on behalf of a victim user. The attacker can craft a malicious link or script that, when clicked by an authenticated user, will send a request to the FlatPress CMS server to perform the desired action on behalf of the victim user. Since the request is authenticated, the server will process it as if it were initiated by the legitimate user, effectively allowing the attacker to perform unauthorized actions. This vulnerability is fixed in version 1.4.dev.

A stored cross-site scripting (XSS) vulnerability exists in flatpressblog/flatpress version 1.3. When a user uploads a file with a `.xsig` extension and directly accesses this file, the server responds with a Content-type of application/octet-stream, leading to the file being processed as an HTML file. This allows an attacker to execute arbitrary JavaScript code, which can be used to steal user cookies, perform HTTP requests, and access content of the same origin.
