CVE-2026-61668Network attack vectorHinoki check available

Arbitrary pilot code execution via unverified TLS downloads

Published Sep 15, 2026 · Updated Sep 15, 2026

Improper certificate validation in DIRAC allows remote attackers to execute arbitrary pilot code through redirected HTTPS downloads. The pilotWrapperScript function creates an unverified TLS context, then fetches both pilot.tar and its reference checksum through that same untrusted channel. Exploitation requires DNS or routing control over a grid site's traffic and runs substituted code with the pilot's proxy credentials.
