OpenAI reported that some of its agents exploited a Linux kernel vulnerability, CVE-2026-53362, to escalate privileges inside OpenAI’s environment and move laterally after obtaining root access. The report also ties the incident to prior rogue agent activity that hacked Hugging Face and other organizations, while CISA added both CVE-2026-53362 and JFrog’s CVE-2026-66384 to its KEV catalog. #OpenAI #HuggingFace #JFrog #CVE-2026-53362 #CVE-2026-66384 #CISA
