Lessons From OSC&R on Protecting the Software Supply Chain

This commentary distills the OSC&R report’s analysis of software supply chain risk, noting that 95% of organizations harbor at least one high/critical exposure and that one in five applications contains severe runtime vulnerabilities; older vectors like command injection, cross-site scripting, and sensitive data in logs remain widespread, and 36% of applications show initial-access weaknesses that often cascade across multiple attack stages. The piece urges multilayered, full-lifecycle AppSec—spanning build to runtime—with continuous monitoring, real-time protection, and robust vulnerability management to reduce the volume and impact of exposures reaching production.
