# Security

<AccordionGroup>
  <Accordion title="hashids-with-flask-secret">
    The Flask secret key is used as salt in HashIDs. The HashID mechanism is not secure. By observing sufficient HashIDs, the salt used to construct them can be recovered. This means the Flask secret key can be obtained by attackers, through the HashIDs.<br />**Likelihood**: LOW<br />**Confidence**: HIGH<br />**CWE**: <br />- CWE-327: Use of a Broken or Risky Cryptographic Algorithm
    <br />**OWASP**: <br />- A02:2021 – Cryptographic Failures
  </Accordion>

  <Accordion title="response-contains-unsanitized-input">
    Flask response reflects unsanitized user input. This could lead to a cross-site scripting vulnerability ([https://owasp.org/www-community/attacks/xss/](https://owasp.org/www-community/attacks/xss/)) in which an attacker causes arbitrary code to be executed in the user's browser. To prevent, please sanitize the user input, e.g. by rendering the response in a Jinja2 template (see considerations in [https://flask.palletsprojects.com/en/1.0.x/security/](https://flask.palletsprojects.com/en/1.0.x/security/)).<br />**Likelihood**: LOW<br />**Confidence**: LOW<br />**CWE**: <br />- CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
    <br />**OWASP**: <br />- A07:2017 - Cross-Site Scripting (XSS)
    <br />- A03:2021 - Injection
  </Accordion>

  <Accordion title="insecure-deserialization">
    Detected the use of an insecure deserialization library in a Flask route. These libraries are prone to code execution vulnerabilities. Ensure user data does not enter this function. To fix this, try to avoid serializing whole objects. Consider instead using a serializer such as JSON.<br />**Likelihood**: LOW<br />**Confidence**: LOW<br />**CWE**: <br />- CWE-502: Deserialization of Untrusted Data
    <br />**OWASP**: <br />- A08:2017 - Insecure Deserialization
    <br />- A08:2021 - Software and Data Integrity Failures
  </Accordion>

  <Accordion title="dangerous-template-string">
    Found a template created with string formatting. This is susceptible to server-side template injection and cross-site scripting attacks.<br />**Likelihood**: LOW<br />**Confidence**: LOW<br />**CWE**: <br />- CWE-96: Improper Neutralization of Directives in Statically Saved Code ('Static Code Injection')
    <br />**OWASP**: <br />- A03:2021 - Injection
  </Accordion>

  <Accordion title="avoid_send_file_without_path_sanitization">
    Detected a user-controlled `filename` that could flow to `flask.send_file()` function. This could lead to an attacker reading arbitrary file from the system, leaking private information. Make sure to properly sanitize filename or use `flask.send_from_directory`<br />**Likelihood**: LOW<br />**Confidence**: LOW<br />**CWE**: <br />- CWE-73: External Control of File Name or Path
    <br />**OWASP**: <br />- A04:2021 - Insecure Design
  </Accordion>

  <Accordion title="flask-api-method-string-format">
    Method $METHOD in API controller $CLASS provides user arg $ARG to requests method $REQMETHOD<br />**Likelihood**: LOW<br />**Confidence**: LOW<br />**CWE**: <br />- CWE-134: Use of Externally-Controlled Format String
  </Accordion>

  <Accordion title="unescaped-template-extension">
    Flask does not automatically escape Jinja templates unless they have .html, .htm, .xml, or .xhtml extensions. This could lead to XSS attacks. Use .html, .htm, .xml, or .xhtml for your template extensions. See [https://flask.palletsprojects.com/en/1.1.x/templating/#jinja-setup](https://flask.palletsprojects.com/en/1.1.x/templating/#jinja-setup) for more information.<br />**Likelihood**: LOW<br />**Confidence**: LOW<br />**CWE**: <br />- CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
    <br />**OWASP**: <br />- A07:2017 - Cross-Site Scripting (XSS)
    <br />- A03:2021 - Injection
  </Accordion>

  <Accordion title="open-redirect">
    Data from request is passed to redirect(). This is an open redirect and could be exploited. Consider using 'url\_for()' to generate links to known locations. If you must use a URL to unknown pages, consider using 'urlparse()' or similar and checking if the 'netloc' property is the same as your site's host name. See the references for more information.<br />**Likelihood**: LOW<br />**Confidence**: LOW<br />**CWE**: <br />- CWE-601: URL Redirection to Untrusted Site ('Open Redirect')
    <br />**OWASP**: <br />- A01:2021 - Broken Access Control
