Vulnerability Rating Taxonomy

Successful customer/researcher collaboration requires a common understanding of risk severity. The Bugcrowd Vulnerability Rating Taxonomy (VRT) provides it.

Key Facts

What is VRT?

The Bugcrowd VRT is an open-source, industry-standard taxonomy that aligns customers and researchers on a common set of risk priority ratings for vulns we see often and edge cases. VRT ratings can also be easily converted to CVSS in the platform. Bugcrowd reviews proposed changes to the VRT from the community on a weekly basis.

Customer Benefits

Faster remediation

The VRT helps customers provide clear guidelines and reward ranges to researchers hunting in their programs. When vulnerabilities are ready to be fixed, customers receive VRT-mapped remediation advice to help fix what’s found, faster.

Researcher Benefits

Rewards transparency

Being transparent about vulnerability priority levels helps researchers optimize their time and effort to work on things they value. For that goal, VRT helps researchers focus on specific vulnerability types based on their objective priority to Bugcrowd customers.
