A Zip Slip vulnerability exists in the Unarchive function of pkg/utils/zip.go in github.com/fission/fission up to version 1.24.0. The function improperly joins archive entry names with the destination directory without validating that the resolved path remains inside the destination. This allows crafted zip entries with directory traversal sequences (e.g., ../../tmp/evil) to write files outside the intended extraction directory. The vulnerability can be triggered when the fetcher downloads and extracts a zip archive, potentially allowing an attacker controlling the archive URL to write files arbitrarily within the file system accessible to the fetcher process.
