Working Groups (WGs) and Special Interest Groups (SIGs)

You may request to join any WG, SIG, or Email Collaboration List included on this page by emailing [email protected]. We look forward to hearing from you!


CWE Community WGs and SIGs

Artificial Intelligence Working Group (AI WG)

The AI WG was established by CWE™ and CVE® community stakeholders to identify and address gaps in the CWE corpus where AI-related weaknesses are not adequately covered, and work collaboratively to fix them.

Request Information/Join


Hardware CWE Special Interest Group (HW CWE SIG)

The HW CWE SIG offers a forum for researchers and representatives from organizations operating in hardware design, manufacturing, and security to interact, share opinions and expertise, and leverage each other’s experiences in supporting the continued growth and adoption of CWE as a common language for defining hardware security weaknesses. The objective of the HW CWE SIG is to establish a stakeholder community for discussing HW CWE content and explore further cross-organizational collaboration opportunities.

Root Cause Mapping Working Group (RCM WG)

The RCM WG was established by CVE® and CWE™ community stakeholders (e.g., Intel, Microsoft, Red Hat, Rapid 7, CISA, HSSEDI) with the purpose of determining how to improve and scale accurate root cause mapping. Specifically, the working group is exploring the feasibility of an effective decentralized root cause mapping ecosystem.

User Experience Working Group (UEWG)

The UEWG is working to develop strategies and solutions for improving how CWE weaknesses are presented, optimizing CWE content, and educating end users.

Email Collaboration Lists

While there is support for ad-hoc working meetings, the following function primarily as mailing lists.

ICS/OT Special Interest Group (ICS/OT SIG)

The ICS/OT SIG email discussion list offers a forum for researchers and technical representatives from organizations operating in industrial control systems (ICS) and operational technology (OT) design, manufacturing, and security to interact, share opinions and expertise, and leverage each other’s experiences in supporting continued growth and adoption of CWE as a common language for defining ICS/OT security weaknesses.

REST API Working Group (REST API WG)

The REST API WG collaborates via the REST API WG email discussion list. The objective of the REST API WG is to ease the interface between security software and hardware architects, EDA tool developers, verification engineers concerned about mitigating security risks in their products; and the databases themselves, by designing a RESTful API. The CWE REST API is available here.

CWE Research Discussion

The CWE Research Discussion Email List is a lightly moderated public forum to discuss CWE definitions, suggest potential definition expansion(s), and/or submit new definitions. General discussion of the vulnerabilities themselves is also welcome.
