FalconFlank Zero-Day Hits CrowdStrike Falcon Sensor

A security researcher published proof-of-concept code for FalconFlank, a zero-day privilege escalation vulnerability affecting CrowdStrike Falcon Sensor on fully patched Windows systems, on GitHub on September 3, 2026. The researcher disclosed the vulnerability publicly without advance notice to CrowdStrike and no CVE identifier has been assigned.

Why it matters: Organizations running CrowdStrike Falcon are exposed to local privilege escalation until the vendor patches; security teams should assess whether the exploit is actively exploited in the wild and prioritize remediation accordingly.
