Vulnerabilities 17
-
High 8.2
rsync 3.0.1 < 3.5.0 Heap Out-of-Bounds Write via read_args()
rsync 3.0.1 before 3.5.0 contains an out-of-bounds write vulnerability in the read_args() function that allows a malicious sender to corrupt adjacent heap memory by sending a crafted argument list. When the argument count causes the argv allocation to be exac…

High 8.2
rsync 3.0.0 < 3.5.0 Out-of-Bounds Write via FLAG_HLINKED Handling
rsync 3.0.0 before 3.5.0 contains an out-of-bounds write vulnerability that allows attackers to corrupt memory by triggering HLINK_BUMP processing on file entries with the FLAG_HLINKED flag set while the hard-link preservation option is inactive. Attackers ca…

High 8.2
rsync 3.2.5 < 3.5.0 Heap Out-of-Bounds Write via files-from Entry
rsync 3.2.5 before 3.5.0 contains a heap out-of-bounds write vulnerability that allows remote unauthenticated attackers to write one attacker-controlled byte past the end of a heap allocation by supplying a crafted files-from entry. Attackers can trigger the …
-
High 8.1
rsync < 3.5.0 TOCTOU Race Condition Directory Escape via rrsync
rsync before 3.5.0 contains a time-of-check to time-of-use (TOCTOU) race condition vulnerability in the rrsync restricted shell wrapper that allows authenticated clients to escape enforced directory restrictions by substituting a symlink for a path component …
-
High 8.1
rsync < 3.5.0 Command Injection via Multiple Code Paths
rsync before 3.5.0 contains multiple command and argument injection vulnerabilities that allow attackers to execute arbitrary commands by supplying malicious input through several code paths, including the RSYNC_CONNECT_PROG environment variable, daemon hooks…
-
High 8.1
rsync < 3.5.0 Arbitrary File Write via --temp-dir/--link-dest
rsync before 3.5.0 contains an arbitrary file write vulnerability that allows attackers to write files outside the intended destination tree by specifying an absolute path via --temp-dir or --link-dest options. The rename-confinement logic is bypassed when th…
-
High 8.1
rsync 2.3.3 < 3.5.0 Path Traversal via --partial-dir/--backup-dir Symlink
rsync 2.3.3 before 3.5.0 contains a path traversal vulnerability that allows a malicious sender to escape the module root by exploiting symlinks within the module file tree when using --partial-dir or --backup-dir options. Attackers with write access to place…
-
High 8.1CVE-2026-70463 Public exploit
rsync 3.1.0 < 3.5.0 Authorization Bypass via auth users Directive Parsing
rsync 3.1.0 before 3.5.0 contains an authorization bypass in auth users directive parsing. The auth users parser uses comma-only tokenization when splitting the user list, which fails to correctly handle entries of the form @Group Name where the group name co…
-
High 7.8
rsync < 3.5.0 Symlink Following Arbitrary File Overwrite
rsync before 3.5.0 contains a symlink following vulnerability that allows local attackers to overwrite arbitrary files by placing a symlink at a predictable output path such as --log-file, --write-batch, or daemon-mode log and statistics paths. Attackers can …
-
High 7.5
rsync < 3.5.0 Algorithmic Complexity DoS via hash_search()
rsync before 3.5.0 contains an algorithmic complexity vulnerability in the hash_search() function that allows a remote attacker to cause a denial of service by delivering a carefully constructed file list. A sender can exploit the quadratic-time worst-case be…
-
High 7.5
rsync 2.0.0 < 3.5.0 Connection Slot Exhaustion DoS via Handshake Stall
rsync daemon 2.0.0 before 3.5.0 contains a denial of service vulnerability that allows unauthenticated remote attackers to exhaust daemon connection slots by stalling the handshake process before or after module selection without triggering the I/O timeout. A…
-
High 7.4
rsync < 3.5.0 Path Confinement Bypass via /./ Boundary Marker in Chroot Mode
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 mar…
-
High 7.4
rsync 3.1.0 < 3.5.0 Access Control Bypass via DNS Resolution Failure
rsync 3.1.0 before 3.5.0 contains an access control bypass vulnerability that allows remote attackers to circumvent hosts deny rules by inducing DNS resolution failures during hostname-based access control evaluation. When a DNS lookup for a hostname-based de…
-
High 7.1
rsync < 3.5.0 Path Traversal via Symlink Module Root
rsync before 3.5.0 contains a path traversal vulnerability that allows remote clients to access files outside the intended module root when use chroot is disabled and the module root path or a component of it is a symlink. The daemon calls chdir() to the modu…
-
High 7.1
rsync < 3.5.0 Path Traversal Write Escape via --relative Mode
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 sy…
-
High 7.1
rsync < 3.5.0 Arbitrary File Read via Symlink Following
rsync before 3.5.0 contains an arbitrary file read vulnerability that allows attackers to read files accessible to the rsync daemon process by exploiting symlink following in input configuration file handling including --files-from, --password-file, and filte…
-
Medium 6.5
rsync < 3.5.0 Arbitrary File Deletion via Malicious File List
rsync before 3.5.0 contains an improper path handling vulnerability that allows a malicious sender to expand the scope of --delete operations beyond the intended destination subtree by sending a crafted file list that causes rsync to reclassify implied parent…
