CVE-2026-53793

rsync < 3.5.0 Path Confinement Bypass via /./ Boundary Marker in Chroot Mode PUBLISHED

Description (CNA)

rsync before 3.5.0 contains a path confinement bypass vulnerability that allows remote clients to escape the intended inner-module root confinement by constructing paths that resolve outside the chroot boundary when the module root contains a /./ boundary marker. Attackers can exploit improper handling of the /./ notation or forge delta-basis transfers referencing xname paths that cross the /./ boundary to gain unauthorized read or write access to files outside the module's subtree.
