SCA: security update for github.com/kedacore/keda, github.com/kedacore/keda/v2 (GHSA-637c-6jxx-4rwm)

critical Tenable Cloud Security Plugin ID 474678

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - KEDA is a Kubernetes-based Event Driven Autoscaling component. In version 2.20.2 and earlier, a namespace
 administrator who can create TriggerAuthentication and ScaledObject resources can set
 hashiCorpVault.address to a tenant-controlled endpoint and select Kubernetes authentication without an
 explicit credential. KEDA then uses the operator pod's projected ServiceAccount token and sends it to that
 endpoint as a Vault login credential. The JWT-shape filter from the prior CVE-2025-68476 remediation
 accepts the operator token because its subject is a Kubernetes ServiceAccount, so the attacker can obtain
 the operator's cluster-wide permissions, including broad Secret reads and workload or admission-related
 operations. This vulnerability is fixed in 2.21.0. (CVE-2026-77524)

Solution

Update the github.com/kedacore/keda/v2 library and its related packages to version 2.21.0 or later.
