    node-tar: Uncontrolled Resource Consumption

    CVE-2026-73566Isaacs

    node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.21, node-tar's filesFilter in src/list.ts uses the recursive mapHas helper to walk an archive entry path upward with path.dirname() and no segment cap when tar.t(...) or tar.x(...) receiv

  • 7.5 High severity

    node-tar: Loop with Unreachable Exit Condition

    CVE-2026-59874Isaacs

    node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.18, tar.replace accepts a checksum-valid tar header with a negative base-256 encoded entry size, causing the archive scanner to make no progress while repeatedly parsing the same header.

  • 7.5 High severity

    node-tar: Allocation of Resources Without Limits or Throttling

    CVE-2026-59873Isaacs

    node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.19, node-tar does not enforce hard upper bounds on total decompressed data, entry counts, or decompression ratio in extraction and parsing paths such as src/extract.ts, allowing a small c

    node-tar: Improper Limitation of a Pathname to a Restricted Directory

    CVE-2026-26960Isaacs

    node-tar is a full-featured Tar for Node.js. When using default options in versions 7.5.7 and below, an attacker-controlled archive can create a hardlink inside the extraction directory that points to a file outside the extraction root, enabling arbitrary file

    brace-expansion: Inefficient Regular Expression Complexity

    CVE-2026-25547Isaacs

    @isaacs/brace-expansion is a hybrid CJS/ESM TypeScript fork of brace-expansion. Prior to version 5.0.1, @isaacs/brace-expansion is vulnerable to a denial of service (DoS) issue caused by unbounded brace range expansion. When an attacker provides a pattern cont

  • 8.2 High severity

    node-tar: Improper Limitation of a Pathname to a Restricted Directory

    CVE-2026-24842Isaacs

    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 maliciou

  • 7.5 High severity

    node-glob: Improper Neutralization of Special Elements used in an OS Command

    CVE-2025-64756IsaacsEPSS 3.09%

    Glob matches files using patterns the shell uses. Starting in version 10.2.0 and prior to versions 10.5.0 and 11.1.0, the glob CLI contains a command injection vulnerability in its -c/--cmd option that allows arbitrary command execution when processing files w
