# A06:2021  - Vulnerable and Outdated Components

> Security rules for Vulnerable and Outdated Components vulnerabilities. Applications that use components with known vulnerabilities may undermine application defenses and enable various attacks. This includes outdated libr

Applications that use components with known vulnerabilities may undermine application defenses and enable various attacks. This includes outdated libraries, frameworks, and other software modules running with known security flaws.

## Detected Vulnerabilities

<AccordionGroup>
  <Accordion title="CWE-1104: Use of Unmaintained Third-Party Components">
    **Severity:** **High**

    ### Description

    The application uses third-party components that are no longer maintained, meaning known vulnerabilities will never be patched by the original maintainer.

    ### Impact

    Unmaintained dependencies accumulate unpatched vulnerabilities over time, creating increasingly severe security risks that require manual mitigation or component replacement.

    ### Remediation

    Regularly audit dependencies for maintenance status. Replace unmaintained components with actively maintained alternatives. Use automated dependency scanning tools. Establish a dependency update policy.
  </Accordion>

  <Accordion title="CWE-937: Use of Components with Known Vulnerabilities">
    **Severity:** **Critical**

    ### Description

    The application includes third-party components (libraries, frameworks, modules) that have known, publicly disclosed security vulnerabilities.

    ### Impact

    Attackers can exploit known CVEs in application dependencies to gain unauthorized access, execute code, or cause denial of service without needing to find new vulnerabilities.

    ### Remediation

    Implement automated dependency scanning in CI/CD pipelines. Subscribe to security advisories for all dependencies. Update vulnerable components promptly. Use lockfiles to ensure reproducible builds.
