Description

CVE-2026-30973 (GHSA-rfx7-4xw3-gh4m) was a plain path traversal in the entry name. The containment check built an Error object without throwing it, so an entry literally named something like ../evil.txt was written outside the destination. That issue was fixed in @appium/support 7.0.6 by actually rejecting out of bound entry names.

Recommendation

Update the @appium/support package to the latest compatible version. Followings are version details:

  • Affected version(s): <= 7.2.5
  • Patched version(s): 7.2.6
