Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The npm package @appium/support, before version 7.2.6, does not check symbolic link targets when extracting ZIP archives, so files can be written outside the extraction directory. An attacker who can supply an archive that Appium extracts can combine a symlink entry with a later file entry to write to any location the Appium process can write, possibly leading to code execution. Upgrade @appium/support to version 7.2.6, which contains the fix.
