Red Hat and IBM used 'Lightwell' to fix 400+ undisclosed Java library vulnerabilities and launch 'Lightwell Clearinghouse' (report)

What happened

Red Hat and IBM used Lightwell to find and fix more than 400 previously unknown vulnerabilities in Java libraries. They also made 'Lightwell Clearinghouse' generally available. The service lets enterprise customers ask for specific open-source dependencies to be reviewed and fixed first. The two companies said the move is a response to the threat of autonomous AI agents chaining several low-risk vulnerabilities into more serious attacks.

Why it matters

As AI automates attacks, large-scale advance patching of the open-source supply chain is now offered as a commercial service.
