Fission: SanitizeFilePath lexical HasPrefix bypass permits sibling-directory escape

SanitizeFilePath in pkg/utils/utils.go validated that a path stayed under a safe directory by calling strings.HasPrefixpath, safedir. This is a lexical check, not a directory boundary check: /packages-extra/evil starts with /packages, so it passed. The function did not enforce a path-separator...

Fission: Zip Slip in pkg/utils/zip.go:Unarchive allows fetcher to write outside the destination directory

Unarchive in pkg/utils/zip.go joined each archive entry name with the destination directory via filepath.Join and wrote the result without checking whether the resolved path stayed under the destination. A zip entry named ../../tmp/evil therefore landed at /tmp/evil. An attacker who could control...

GHSA-VCHH-R53J-8MPW Fission: HTTPTrigger admission omits RelativeURL / Prefix validation; kubectl apply bypasses CLI checks

HTTPTriggerSpec.Validate validated Methods, FunctionReference, Host, IngressConfig, and CorsConfig, but silently skipped RelativeURL and Prefix. Those two fields were validated at the CLI level only pkg/fission-cli/cmd/httptrigger/create.go:83. The post-CRD-modernization webhook for HTTPTrigger w...
