CVE-2026-79776

Estado: Pendiente de análisisMedia (6.9)—

rclone before 1.75.0 mounts the pprof debug handler as its own router route, bypassing the fail-closed authentication rule in the main handler. Attackers can access the /debug/pprof/cmdline endpoint unauthenticated to retrieve the full process argv including backend credentials.

CVSS

Probabilidad de explotación (EPSS)
