Summary

Security context

CVE-2026-26960 / GHSA-83g3-92jg-28cx — High severity (CVSS 7.1)

Arbitrary file read/write via hardlink target escape through symlink chain in node-tar extraction. Fixed in tar@7.5.8.

The action itself does not call tar.extract() at runtime, so exploitability is low. However, the vulnerable package was present as a transitive dependency via cacache and node-gyp (build toolchain), and the previous resolution pin (>=7.5.7) missed the fix by one patch version.

Test plan

  • yarn install completes successfully
  • yarn.lock resolves tar to 7.5.11
  • CI build passes

Closes crazy-max#16 (Dependabot alert)

🤖 Generated with Claude Code

Fixes Dependabot alert crazy-max#16. Upgrades the yarn resolution override for
tar from >=7.5.7 to >=7.5.8 to address CVE-2026-26960 (arbitrary file
read/write via hardlink target escape through symlink chain). Lockfile
now resolves to tar@7.5.11.
