Senserva AI Opinion for CVE-2025-6218

WinRAR extracts archive contents to attacker-chosen paths through this path traversal, letting a booby-trapped archive plant code that executes as the current user, typically via startup folder drops. It is rated High Severity at CVSS 7.8 with an 86% EPSS score and has been confirmed exploited since 2025-12-09. WinRAR has no auto-update mechanism, so vulnerable versions persist on end user machines for years unless IT replaces them.

Do this: Push an updated WinRAR to all endpoints through software deployment and remind users that archives from email are executable content.
