Arbitrary file deletion via origin validation error
Published Oct 8, 2025 · Updated Oct 8, 2025
Origin validation error in CrowdStrike Falcon Sensor for Windows allows local users with prior code execution to delete arbitrary files. The sensor processes untrusted input with faulty origin-validation logic that can redirect a privileged file-deletion operation, although CrowdStrike has not disclosed the exact code locus or input format. Successful exploitation requires existing local code execution and can interrupt the sensor, other software, or Windows by removing files.
