# Tainted pyyaml aws lambda

<AccordionGroup>
  <Accordion title="tainted-pyyaml-aws-lambda">
    The application may convert user-controlled data into an object, which can lead to an insecure deserialization vulnerability. An attacker can create a malicious serialized object, pass it to the application, and take advantage of the deserialization process to perform Denial-of-service (DoS), Remote code execution (RCE), or bypass access control measures. PyYAML's `yaml` module is as powerful as `pickle` and so may call auny Python function. It is recommended to secure your application by using `yaml.SafeLoader` or `yaml.CSafeLoader`.<br />**Likelihood**: MEDIUM<br />**Confidence**: HIGH<br />**CWE**: <br />- CWE-502: Deserialization of Untrusted Data
    <br />**OWASP**: <br />- A08:2017 - Insecure Deserialization
    <br />- A08:2021 - Software and Data Integrity Failures
