When these posts are viewed, the content is rendered using the Jinja2 `|safe` filter, which disables auto-escaping. This allows an attacker to execute malicious scripts in the context of any user viewing the post, potentially leading to session hijacking or unauthorized actions. + +PoC +```python +import requests + +# Assuming the attacker has access to create a post (or via CSRF) +session = requests.Session() +# Login if necessary, or exploit missing CSRF +session.post("http://127.0.0.1:5000/login", data={"username": "admin", "password": "admin"}) +session.post("http://127.0.0.1:5000/create_post", data={ + "title": "Malicious Post", + "author": "Attacker", + "tags": "test", + "content": "" +}) + +# When any user visits /post/Malicious%20Post, the script will execute. +r = requests.get("http://127.0.0.1:5000/post/Malicious%20Post") +if "" in r.text: + print("XSS Vulnerability Confirmed") +``` + +Fix +Remove the `|safe` filter from `html/post.html` and use a dedicated library like `bleach` to sanitize the HTML output of `markdown2` before passing it to the template. + +--- + +MEDIUM - Missing CSRF Protection +The application lacks Cross-Site Request Forgery (CSRF) protection on state-changing routes such as `/login`, `/create_post`, and `/upload`. An attacker can trick a logged-in administrator into performing actions like creating a malicious post or uploading files by enticing them to visit a specially crafted website. + +PoC +```python +# A simple HTML form hosted on an attacker's site can trigger a post creation +#
