secure-set-cookie

Found a Flask cookie with insecurely configured properties. By default the secure, httponly and samesite ar configured insecurely. cookies should be handled securely by setting secure=True, httponly=True, and samesite='Lax' in response.set_cookie(…). If these parameters are not properly set, your cookies are not properly protected and are at risk of being stolen by an attacker. Include the secure=True, httponly=True, samesite='Lax' arguments or set these to be true in the Flask configuration.
Likelihood: LOW
Confidence: LOW
CWE:
- CWE-614: Sensitive Cookie in HTTPS Session Without ‘Secure’ Attribute
OWASP:
- A05:2021 - Security Misconfiguration

directly-returned-format-string

Detected Flask route directly returning a formatted string. This is subject to cross-site scripting if user input can reach the string. Consider using the template engine instead and rendering pages with ‘render_template()’.
Likelihood: HIGH
Confidence: MEDIUM

- CWE-79: Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’)
OWASP:
- A07:2017 - Cross-Site Scripting (XSS)

CWE:
- CWE-668: Exposure of Resource to Wrong Sphere
OWASP:
- A01:2021 - Broken Access Control

flask-wtf-csrf-disabled

Setting ‘WTF_CSRF_ENABLED’ to ‘False’ explicitly disables CSRF protection.
Likelihood: LOW
Confidence: LOW
CWE:
- CWE-352: Cross-Site Request Forgery (CSRF)
OWASP:
- A01:2021 - Broken Access Control

render-template-string

Found a template created with string formatting. This is susceptible to server-side template injection and cross-site scripting attacks.
Likelihood: LOW
Confidence: LOW
CWE:
- CWE-96: Improper Neutralization of Directives in Statically Saved Code (‘Static Code Injection’)
OWASP:
- A03:2021 - Injection

avoid_using_app_run_directly

top-level app.run(…) is ignored by flask. Consider putting app.run(…) behind a guard, like inside a function
Likelihood: LOW
Confidence: MEDIUM

- CWE-668: Exposure of Resource to Wrong Sphere
OWASP:
- A01:2021 - Broken Access Control

host-header-injection-python

The flask.request.host is used to construct an HTTP request. This can lead to host header injection issues. Vulnerabilities that generally occur due to this issue are authentication bypasses, password reset issues, Server-Side-Request-Forgery (SSRF), and many more. It is recommended to validate the URL before passing it to a request library, or using application logic such as authentication or password resets.
Likelihood: LOW
Confidence: LOW
CWE:
- CWE-20: Improper Input Validation
