CVE-2024-28863 Generating a large number of sub-folders can consume memory on the system and even crash the Node.js client within a few seconds using a path with too many sub-folders inside. CVE-2026-23745 When preservePaths is false, the linkpath of Link (hardlink) and SymbolicLink entries fail to be sanitized, allowing malicious archives to bypass the extraction root restriction, leading to arbitrary file overwrites via hardlinks and symlink poisoning via absolute symlink targets. The fix for this issue introduces multiple of the following vulnerabilties. CVE-2026-24842 The security check for hardlink entries allows an attacker to craft a malicious TAR archive that bypasses path traversal protections and creates hardlinks to arbitrary files outside the extraction directory. CVE-2026-26960 An attacker-controlled archive can create a hardlink inside the extraction directory that points to a file outside the extraction root, enabling arbitrary file read and write as the extracting user. CVE-2026-29786 Anattacker-controlled archive can create a hardlink that points outside the extraction directory by using a drive-relative link target. CVE-2026-31802 An attacker-controlled archive can create a hardlink that points outside the extraction directory by using a drive-relative link target. For Debian 11 bullseye, these problems have been fixed in version 6.0.5+ds1+~cs11.3.9-1+deb11u3. We recommend that you upgrade your node-tar packages.
