Deep Dive - CRA Requirement (5) Coordinated Vulnerability Disclosure Policy

The fifth vulnerability-handling requirement under the EU Cyber Resilience Act (CRA) obliges manufacturers to establish and enforce a Coordinated Vulnerability Disclosure (CVD) policy.

“(5) put in place and enforce a policy on coordinated vulnerability disclosure;”

This requirement sets the expectation that vulnerability reporting should not be an informal or ad hoc process. Instead, every manufacturer must have a clearly defined policy and process that explains how vulnerabilities can be reported, who is responsible for handling them, and how stakeholders will be informed. In short, the CRA makes CVD a regulatory obligation, turning good practice into mandatory practice.

What this requirement means

Think of it like an emergency hotline: if someone notices a fire in your building, they need a clear way to reach the fire department. Similarly, if somebody identifies a flaw in your connected product, the CVD policy defines the channel to report it, the expectations for handling it, and how the outcome will be communicated.

For manufacturers, this requirement means that they must publish a clear vulnerability disclosure policy that is easy for all stakeholders to find and understand. They need to define roles and responsibilities within their organization to ensure it is clear who receives, triages, and responds to vulnerability reports. In addition, manufacturers are expected to coordinate with external stakeholders such as security researchers, national CSIRTs, and customers in a structured and transparent manner. Finally, they must ensure that vulnerabilities are handled responsibly and that disclosure is not delayed unnecessarily.

Relevant Standards and Guidelines

Although the CRA does not prescribe a single standard, several existing frameworks can support compliance with this requirement:

• EN ISO/IEC 29147: provides guidelines for developing and implementing vulnerability disclosure processes, including roles, responsibilities, and communication. It supports the creation of a CVD policy but does not define detailed industry-specific processes.

• EN ISO/IEC 30111: complements 29147 by focusing on vulnerability handling processes, investigating, resolving, and disclosing vulnerabilities in a coordinated manner, but does not address enforcement of EU or national CVD policies.

• ETSI EN 303 645: (for consumer IoT) requires mechanisms for managing vulnerability reports and references ISO/IEC 29147, but remains generic in how CVD should be applied to IoT contexts.

Taken together, these standards provide strong foundations for establishing disclosure processes, but as ENISA’s mapping highlights, gaps remain in how CVD policies should be enforced across different industries and product types. To close this gap, manufacturers should align with industry best practices (e.g. NIST SP 800-61 Rev. 3, FIRST VRDX SIG) and national/EU CVD frameworks to ensure consistency and credibility.

How to approach Implementation

To meet this requirement, manufacturers should begin by publishing a Coordinated Vulnerability Disclosure (CVD) policy and making it easily accessible on the company website. This policy should include clear instructions on how vulnerabilities can be reported. They should also define a single point of contact, for example by providing a dedicated email address or a web form. ENISA provides practical resources and guidance that can serve as a strong starting point for building an effective vulnerability management process and CVD policy.

It is important to set clear expectations for timelines by acknowledging the receipt of vulnerability reports quickly, communicating the planned remediation steps, and agreeing on coordinated disclosure timelines with researchers. The CVD policy should also be fully integrated into the company’s internal processes, supported by a robust workflow that covers triage, classification, remediation, and disclosure.

Finally, manufacturers should actively engage with external stakeholders such as CSIRTs and security researchers to ensure that vulnerabilities are disclosed responsibly and that public communication is coordinated. By embedding CVD into the product lifecycle and governance processes, manufacturers not only comply with CRA requirements but also strengthen their overall security posture and build trust with users and partners.

Strategic Considerations beyond Compliance

For many companies, adopting a CVD policy can feel daunting, it means opening a direct channel for people to report flaws in your products. But the alternative is worse: vulnerabilities discovered but not reported through safe channels may end up exploited or published irresponsibly.

The CRA turns CVD into a strategic opportunity. Organizations that implement and enforce a clear policy show customers and partners that they take security seriously. Instead of being seen as a sign of weakness, vulnerability reports become proof of a mature, collaborative approach to security.

Beyond compliance, a strong CVD process fosters trust with the security community, accelerates vulnerability remediation, and demonstrates accountability. In a competitive market, companies known for transparent and responsive disclosure practices will stand out as reliable and trustworthy partners.
