Name of the Vulnerable Software and Affected Versions rsync versions 3.0.0 through 3.4.x Description A null pointer dereference occurs in the daemon child process. A remote attacker can cause the daemon to crash by sending a file list where the first entry is a dot entry not typed as a directory...

CVE-2026-70459: Use of Uninitialized Resource

rsync 3.0.0 before 3.5.0 contains a null pointer dereference vulnerability in the daemon child process that allows remote attackers to crash the daemon by sending a file list whose first entry is a dot entry not typed as a directory. The daemon dereferences the first file list entry as a director...

CVE-2026-53783

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 after validation but before transfer...

PT-2026-71631

Name of the Vulnerable Software and Affected Versions rsync versions prior to 3.5.0 Description A path confinement bypass allows remote clients to escape the intended inner-module root confinement. This occurs when the module root contains a /./ boundary marker, enabling the construction of paths...

Name of the Vulnerable Software and Affected Versions rsync daemon versions 2.0.0 through 3.4.9 Description A denial of service issue exists that allows unauthenticated remote attackers to exhaust daemon connection slots. This is achieved by stalling the handshake process either before or after...

CVE-2026-53790: Improper Neutralization of Special Elements used in an OS Command

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 RSYNCCONNECTPROG environment variable, daemon hooks, the rsync-ssl wrapper, and remote-shel...

PT-2026-71639

Name of the Vulnerable Software and Affected Versions rsync versions prior to 3.5.0 Description A symlink race condition exists in the sender's directory scanning logic. This occurs when an attacker manipulates symlinks in a path component of the scanned tree, replacing a symlink with a directory...

Name of the Vulnerable Software and Affected Versions rsync versions 3.1.0 through 3.4.x Description An authorization bypass exists in the parsing of the auth users directive. The parser utilizes comma-only tokenization when splitting the user list, which fails to correctly process entries...

CVE-2026-53803: Improper Link Resolution Before File Access

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 exploit rsync's failure to reject...

CVE-2026-53793: Improper Link Resolution Before File Access

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...

CVE-2026-53783: Improper Link Resolution Before File Access

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 after validation but before transfer...

CVE-2026-53802: UNIX Symbolic Link (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 filter merge files. Attackers can place a...

PT-2026-71624

Name of the Vulnerable Software and Affected Versions rsync versions prior to 3.5.0 Description A path traversal issue exists when using --relative mode. A malicious sender can write files outside the intended destination directory tree by crafting relative paths containing symlink components. Th...

CVE-2026-53789: Reliance on Untrusted Inputs in a Security Decision

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 directory entries or treat synthetic...

CVE-2026-53802

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 filter merge files. Attackers can place a...
