Since the session cookie is not set to `SameSite: strict`, this opens the library up to severe attack possibilities via a Cross-Site Request Forgery (CSRF) attack. This proof of concept shows how an unauthenticated user could trick the administrator's browser into creating a new admin user. ### PoC We host the following HTML file on an attacker-controlled server. ```html ``` If we now trick an administrator into visiting our malicious page at `https://attacker.com/CSRF.html`, we see that their browser will make a request to `/api/add_user/%22hacker%22,%22hacker%22`, adding a new administrator to the `pyload` application. ![image](https://user-images.githubusercontent.com/44903767/294942232-d874e838-f8eb-492f-98df-2d16ba74ff25.png) The attacker can now authenticate as this newly created administrator user with the username `hacker` and password `hacker`. ![image](https://user-images.githubusercontent.com/44903767/294942635-c6d9adca-0f3a-4d99-92ac-6d3bf8e9ee01.png) ### Impact Any API call can be made via a CSRF attack by an unauthenticated user. ## Affected packages - `pyload-ng < 0.5.0b3.dev78` ## Remediation Upgrade to a patched release: - `pyload-ng 0.5.0b3.dev78`
