Kerentanan Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') pada max-mapper extract-zip. Skor CVSS 3.1 8.1 (High) menurut CNA.

Deskripsi (NVD)

extract-zip does not validate symlink targets when extracting zip archives. When processing a malicious zip file containing a symlink with a relative path like '../../../../etc/passwd', extract-zip will extract the symlink without validation, allowing it to point outside the extraction directory. Depending on how extract-zip is used, an attacker could read or write to arbitrary files.
