Interesting vulnerability in Rapid7's Insight Agent for Linux. CVE-2026-4837 is an eval() injection that could theoretically allow remote code execution as root. The catch? An attacker would need highly privileged access to the Rapid7 backend platform to craft a malicious beacon response. So it's not something random attackers can exploit, but if someone compromises the backend, they could own every Linux system running the agent. It's a high-impact scenario that shows how security tools themselves can become attack vectors. https://www.sentinelone.com/vulnerability-database/cve-2026-4837/
