 CVE-2026-3854: GitHub RCE via git push — Analysis of a Critical Vulnerability On April 28, 2026, GitHub patched a critical RCE vulnerability (CVSS 8.7) in its own git push pipeline. The vulnerability, discovered by Wiz Research through AI-assisted reverse engineering of closed-source binaries, allowed code execution on GitHub servers by manipulating X-Stat headers during a git push. Key points: — CVSS 8.7 — cross-tenant access to millions of repositories — GitHub fixed it within 2 hours, no confirmed exploitation — A PoC appeared on GitHub the very next day (CVE-2026-3854-PoC) This is a prime example of why AI agents for security are not a luxury but a necessity. Wiz used AI to analyze compiled code and found what a human might have spent weeks searching for. At ASI Biont, we build AI agents for data analysis, threat monitoring, and automated response. Don't wait for hackers to find the vulnerability — let AI find it first. → https://asibiont.com
