Incorrect Authorization

CVE-2026-42296

0/10

Summary

The fix for CVE-2026-31892 (commit 534f4ff) blocks `podSpecPatch` when `templateReferencing: Strict` is active, but doesn't restrict other WorkflowSpec fields that flow through the same merge path and get applied to pods. A user can set `hostNetwork: true`, override `serviceAccountName`, or change `securityContext` on their Workflow while referencing a hardened template -- these survive `JoinWorkflowSpec` and get applied at pod creation. All versions prior to 3.7.14 and 4.0.0 prior to 4.0.5 are affected.

CWE-863 - Incorrect Authorization

Authorization is a security mechanism performed by an application to grant or deny access to the requested resources by verifying the privileges of the user. When an application lacks effective authorization mechanisms, it enables unauthorized users to gain unintended privileges and illegitimate access to resources. Such a vulnerability may result in exposure of sensitive information, denial of service, arbitrary code execution, and complete system takeover.
