Auto Security Analysis of app at 2026-02-22
CRITICAL - Stored Cross-Site Scripting (XSS)
The application renders blog post content using the `|safe` filter in Jinja2 templates and the `markdown2` library without sanitization. This allows an attacker to inject malicious scripts into blog posts. When a user or admin views the compromised post, the script executes in their browser, potentially leading to session hijacking or other malicious actions.

PoC
```python
import requests

# Assuming the attacker has gained access or uses CSRF to post
# This payload will trigger an alert in the victim's browser
payload = {
'title': 'Malicious Post',
'author': 'Attacker',
'tags': 'xss',
'content': '<script>alert("XSS")</script>'
}

# In a real scenario, this would be sent via a CSRF attack or by an authenticated user
# requests.post(\'http://localhost:5000/create_post\', data=payload)
```

Fix
Use a sanitization library like `bleach` to clean the HTML generated by `markdown2` before passing it to the template, and remove the `|safe` filter or ensure only safe tags are allowed.

MEDIUM - Cross-Site Request Forgery (CSRF)
The application lacks CSRF protection on critical state-changing routes such as `/create_post`, `/upload`, and `/login`. An attacker can trick a logged-in administrator into visiting a malicious website that submits a hidden form to the blog, creating unauthorized posts or uploading files on behalf of the admin.

PoC
```python
# HTML snippet for a CSRF attack to create a malicious post
# <body onload="document.forms[0].submit()">
# <form action="http://localhost:5000/create_post" method="POST">
# <input type="hidden" name="title" value="CSRF Post" />
# <input type="hidden" name="author" value="Admin" />
# <input type="hidden" name="tags" value="csrf" />
# <input type="hidden" name="content" value="This post was created via CSRF!" />
# </form>
# </body>
```

Fix
Implement CSRF protection using a library like `Flask-WTF` or `Flask-SeaSurf`, which adds a unique token to each form and verifies it on the server side.

MEDIUM - Path Traversal
The `/post/<name>` route uses the user-provided `name` parameter to construct a file path using `os.path.join` without sufficient validation. Although Flask's default routing limits the use of slashes, the logic itself is vulnerable and could allow reading arbitrary `.md` files on the system if the application is misconfigured or if a different routing mechanism is used.

PoC
```python
import requests

# Attempting to read the README.md file located in the root directory
# by traversing up from the articles directory.
# Note: This might be blocked by Flask's default routing if the parameter contains slashes.
target_url = "http://localhost:5000/post/../README"
# response = requests.get(target_url)
# print(response.text)
```

Fix
Validate that the requested file resides within the intended directory using `os.path.abspath` and checking the prefix, or use `werkzeug.utils.safe_join`.
