Aliases CVE-2026-28453
Summary OpenClaw has Zip Slip path traversal in tar archive extraction ## Summary OpenClaw versions before 2026.2.14 did not sufficiently validate TAR archive entry paths during extraction. A crafted archive could use path traversal sequences (for example `../../...`) to write files outside the intended destination directory (Zip Slip). ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected: `< 2026.2.14` - Fixed: `>= 2026.2.14` ## Details The affected code path is `extractArchive()` in `src/infra/archive.ts`. Prior to 2026.2.14, TAR extraction used `tar.x({ cwd: destDir })` without rejecting traversal and absolute entry paths. This extraction is used by installation flows such as: - `openclaw plugins install …` - `openclaw hooks install …` ## Impact If a user installs an untrusted `.tar` / `.tgz` archive, an attacker can write files outside the extraction directory (within the permissions of the OpenClaw process). This can lead to configuration tampering and potentially code execution. ## Mitigation Upgrade to `openclaw >= 2026.2.14`. Avoid installing untrusted plugin/hook archives. ## Fix Commit(s) - `3aa94afcfd12104c683c9cad81faf434d0dadf87` OpenClaw thanks @xuemian168 for reporting.
