CVE-2026-29786 node-tar: Hardlink Path Traversal via Drive-Relative Linkpath

node-tar is a full-featured Tar for Node.js. Prior to version 7.5.10, tar can be tricked into creating a hardlink that points outside the extraction directory by using a drive-relative link target such as C:../target.txt, which enables file overwrite outside cwd during normal tar.x extraction. Th...

Important: nodejs22

Issue Overview: 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...

Important: nodejs20

Issue Overview: 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...

GHSA-3JX4-Q2M7-R496 OpenClaw: Hardlink alias checks could bypass workspace-only file boundaries in specific configurations

Summary In certain workspace-restricted configurations, OpenClaw could follow hardlink aliases inside the workspace that reference files outside the workspace boundary. By default, tools.fs.workspaceOnly is off. This primarily affects deployments that intentionally enable workspace-only filesyste...
