Claude Opus Discovers Over 500 High Severity Vulnerabilities in Open Source Codebases

An announcement regarding Claude Opus 4.6 reports that the model was used to identify approximately 500 high severity vulnerabilities in open source libraries. The affected libraries include Ghostscript (a PDF/PostScript interpreter embedded in Linux distributions, printers, and document processors), OpenSC (a middleware for smart card authentication and PKCS#11 in enterprise PKI configurations), and CGIF (a GIF image processing utility). The post's author expresses having been skeptical about LLMs in cybersecurity, but considers this discovery as potentially revolutionary.
