In versions 1.4.3 and below, attackers can trigger SSRF to arbitrary internal services because /api/v1/index/retrieve supports retrieving a public key via user-provided URL. Since the SSRF only can trigger GET requests, the request cannot mutate state. The response from the GET request is not returned to the caller so data exfiltration is not possible. A malicious actor could attempt to probe an internal network through Blind SSRF. ## Vendor advisories - **RHSA-2026:37387** · Red Hat · fixed in: Red Hat Openshift Data Foundation 4.22 · released 2026-07-09 · [advisory](https://access.redhat.com/errata/RHSA-2026:37387) - **Red Hat VEX** · Moderate · affected: Assisted Installer for Red Hat OpenShift Container Platform 2, Confidential Compute Attestation, Kernel Module Management Operator for Red Hat Openshift, Logging Subsystem for Red Hat OpenShift, Migration Toolkit for Containers, Migration Toolkit for Virtualization, … · no fix planned: Assisted Installer for Red Hat OpenShift Container Platform 2, Confidential Compute Attestation, Kernel Module Management Operator for Red Hat Openshift, Logging Subsystem for Red Hat OpenShift, … · updated 2026-09-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-24117.json) **github.com/sigstore/rekor: Rekor Server-Side Request Forgery (SSRF)** — rated Moderate by Red Hat.
