Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.23.0, the Fission router registers an internal-style route — /fission-function/ and /fission-function// — for every Function object,...

CVE-2026-46618

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.23.0, before the round-1 security sweep, pkg/builder/builder.go passed Environment.spec.builder.command directly into exec.Command...

CVE-2026-50570

Fission prior to v1.25.0 allowed tenant-created Function/Environment CRDs to request securityContext.capabilities.add: ["SYS_TIME"] despite a fixed denylist (SYS_ADMIN, NET_ADMIN, SYS_PTRACE, SYS_MODULE, DAC_READ_SEARCH, DAC_OVERRIDE). The validation/merge-layer sanitization did not block CAP_SYS...

CVE-2026-50569

The CVE concerns Fission (Kubernetes-native serverless framework). Before version 1.25.0, HTTPTriggerSpec.Validate() checked Methods, FunctionReference, Host, IngressConfig, and CorsConfig but silently skipped RelativeURL and Prefix; these fields were only validated at the CLI. As a result, an HT...

CVE-2026-50569 Fission: HTTPTrigger admission omits RelativeURL / Prefix validation; kubectl apply bypasses CLI checks

Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of functions and applications on Kubernetes. Prior to version 1.25.0, HTTPTriggerSpec.Validate validated Methods, FunctionReference, Host, IngressConfig, and CorsConfig, but silently skipped RelativeU...

CVE-2026-50568

Fission (Kubernetes-native serverless framework) has a lexical path check vulnerability in SanitizeFilePath (pkg/utils/utils.go) that used strings.HasPrefix(path, safedir) instead of a directory-boundary check. This allowed a sibling directory escape (e.g., /packages-extra/evil under /packages) t...

CVE-2026-50567

CVE-2026-50567 affects Fission prior to 1.25.0. The vulnerability resides in Unarchive (pkg/utils/zip.go) where archive entry paths are joined with the destination path without validating that the final path stays under the destination. An attacker who can control a Package.Spec.Source.URL or Dep...
