It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1464 advisory.

    node-tar is a Tar for Node.js. The node-tar library (<= 7.5.2) fails to sanitize the linkpath of Link     (hardlink) and SymbolicLink entries when preservePaths is false (the default secure behavior). This allows     malicious archives to bypass the extraction root restriction, leading to Arbitrary File Overwrite via     hardlinks and Symlink Poisoning via absolute symlink targets. This vulnerability is fixed in 7.5.3.
    (CVE-2026-23745)

    node-tar,a Tar for Node.js, has a race condition vulnerability in versions up to and including 7.5.3. This     is due to an incomplete handling of Unicode path collisions in the `path-reservations` system. On case-     insensitive or normalization-insensitive filesystems (such as macOS APFS, In which it has been tested),     the library fails to lock colliding paths (e.g., `ss` and `ss`), allowing them to be processed in     parallel. This bypasses the library's internal concurrency safeguards and permits Symlink Poisoning     attacks via race conditions. The library uses a `PathReservations` system to ensure that metadata checks     and file operations for the same path are serialized. This prevents race conditions where one entry might     clobber another concurrently. This is a Race Condition which enables Arbitrary File Overwrite. This     vulnerability affects users and systems using node-tar on macOS (APFS/HFS+). Because of using `NFD`     Unicode normalization (in which `ss` and `ss` are different), conflicting paths do not have their order     properly preserved under filesystems that ignore Unicode normalization (e.g., APFS (in which `ss` causes     an inode collision with `ss`)). This enables an attacker to circumvent internal parallelization locks     (`PathReservations`) using conflicting filenames within a malicious tar archive. The patch in version     7.5.4 updates `path-reservations.js` to use a normalization form that matches the target filesystem's     behavior (e.g., `NFKD`), followed by first `toLocaleLowerCase('en')` and then `toLocaleUpperCase('en')`.
    As a workaround, users who cannot upgrade promptly, and who are programmatically using `node-tar` to     extract arbitrary tarball data should filter out all `SymbolicLink` entries (as npm does) to defend     against arbitrary file writes via this file system entry name collision issue.

    A vulnerability was found in juliangruber brace-expansion up to 1.1.11/2.0.1/3.0.0/4.0.0. It has been     rated as problematic. Affected by this issue is the function expand of the file index.js. The manipulation     leads to inefficient regular expression complexity. The attack may be launched remotely. The complexity of     an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the     public and may be used. Upgrading to version 1.1.12, 2.0.2, 3.0.1 and 4.0.1 is able to address this issue.
    The name of the patch is a5b98a4f30d7813266b221435e1eaaf25a1b0ac5. It is recommended to upgrade the     affected component. (CVE-2025-5889)

    node-tar,a Tar for Node.js, contains a vulnerability in versions prior to 7.5.7 where the security check     for hardlink entries uses different path resolution semantics than the actual hardlink creation logic.
    This mismatch allows an attacker to craft a malicious TAR archive that bypasses path traversal protections     and creates hardlinks to arbitrary files outside the extraction directory. Version 7.5.7 contains a fix     for the issue. (CVE-2026-24842)
