CVE-2026-70622 · tar-rs 0.4.11 - 0.4.46 Symlink Escape via append_dir_all()

Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.

tar-rs versions 0.4.11 through 0.4.46 contain a symlink escape vulnerability in the Builder::append_dir_all() function that allows attackers to read files outside the intended source root directory by planting symlinks in an attacker-controlled directory. When a privileged process archives an untrusted directory, the function follows symlinks without verifying that resolved targets remain within the source root, causing out-of-bounds files to be included in the archive as regular files and disclosed to the attacker.
