Kerentanan Improper Link Resolution Before File Access ('Link Following'). Skor CVSS 3.1 6.5 (Medium) menurut vulncheck.com.

Deskripsi (NVD)

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.
