CVE-2025-8088
RARLAB WinRAR Path Traversal Vulnerability. Exploitation in the wild is confirmed by CISA, not predicted, and the vulnerability is known to be used in ransomware campaigns. Federal agencies were required to remediate by 2025-09-02 (that deadline has passed); treat that date as the outer bound for your own environment. Check the vendor security advisory for the fix.
Risk summary
Actively exploited RARLAB WinRAR vulnerability, High severity, CVSS 8.8. Added to the CISA KEV catalog 2025-08-12.
Senserva AI Opinion for CVE-2025-8088
WinRAR's Windows build has a path traversal where a crafted archive plants files outside the chosen extraction folder, the kind of primitive that drops payloads into autostart locations; CVSS 8.8, EPSS 86%. Exploitation has been confirmed since August 2025, and WinRAR does not update itself, so old copies linger on endpoints for years.
Do this: Push an updated WinRAR to all Windows endpoints through software deployment tooling rather than relying on users.
