{"id":"DEBIAN-CVE-2026-53785","details":"rsync before 3.5.0 contains a path traversal vulnerability that allows a malicious sender to write files outside the intended destination directory tree by crafting relative paths with symlink components in --relative mode. The make_path() function follows symlinks pointing outside the destination tree while creating intermediate directories without verifying that created paths remain within the destination boundary, enabling arbitrary file writes on the receiver's filesystem.","modified":"2026-09-09T08:47:29.968844434Z","published":"2026-08-13T15:19:42.403Z","upstream":["CVE-2026-53785"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-53785"}],"affected":[{"package":{"name":"rsync","ecosystem":"Debian:12","purl":"pkg:deb/debian/rsync?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.7-1","3.2.7-1+deb12u1","3.2.7-1+deb12u2","3.2.7-1+deb12u3","3.2.7-1+deb12u4","3.2.7-1+deb12u5","3.2.7-1+deb12u6","3.3.0+ds1-1","3.3.0+ds1-2","3.3.0+ds1-3","3.3.0+ds1-4","3.3.0-1","3.4.1+ds1-1","3.4.1+ds1-2","3.4.1+ds1-3","3.4.1+ds1-4","3.4.1+ds1-4~exp1","3.4.1+ds1-4~exp2","3.4.1+ds1-5","3.4.1+ds1-5~exp1","3.4.1+ds1-6","3.4.1+ds1-7","3.4.1+ds1-8~exp1","3.4.2+ds1-1","3.4.2+ds1-2","3.4.3+ds1-1","3.4.3+ds1-2","3.4.4+ds1-1","3.5.0+ds1-1","3.5.0+ds1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-53785.json"}},{"package":{"name":"rsync","ecosystem":"Debian:13","purl":"pkg:deb/debian/rsync?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.4.1+ds1-5","3.4.1+ds1-5+deb13u1","3.4.1+ds1-5+deb13u2","3.4.1+ds1-5+deb13u3","3.4.1+ds1-5+deb13u4","3.4.1+ds1-6","3.4.1+ds1-7","3.4.1+ds1-8~exp1","3.4.2+ds1-1","3.4.2+ds1-2","3.4.3+ds1-1","3.4.3+ds1-2","3.4.4+ds1-1","3.5.0+ds1-1","3.5.0+ds1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-53785.json"}},{"package":{"name":"rsync","ecosystem":"Debian:14","purl":"pkg:deb/debian/rsync?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.0+ds1-1"}]}],"versions":["3.4.1+ds1-5","3.4.1+ds1-6","3.4.1+ds1-7","3.4.1+ds1-8~exp1","3.4.2+ds1-1","3.4.2+ds1-2","3.4.3+ds1-1","3.4.3+ds1-2","3.4.4+ds1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-53785.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
