Red Hat Security Advisory: zero trust workload identity manager for Red Hat OpenShift 1.0.1
Severity
Important
Notes
Topic: zero trust workload identity manager for Red Hat OpenShift 1.0.1
Details: The Zero Trust Workload Identity Manager (ZTWIM) is a day-2 operator. The operator manages lifecycle of operand components from SPIRE project. The goal of ZTWIM is to provide secure, verifiable workload identities for workloads in multi-cloud environments. The operand components automate identity issuance, rotation, and verification, enhancing the zero-trust security model while eliminating static credentials. The current release of zero trust workload identity manager for Red Hat OpenShift is for Technology Preview.

CVE-2025-61726

A flaw was found in the net/url package in the Go standard library. The package does not enforce a limit on the number of unique query parameters it parses. A Go application using the net/http.Request.ParseForm method will try to process all parameters provided in the request. A specially crafted HTTP request containing a massive number of query parameters will cause the application to consume an excessive amount of memory, eventually causing the application to crash or become unresponsive, resulting in a denial of service.

CVE-2026-21441

A flaw was found in urllib3. When processing HTTP redirect responses during data streaming, the library automatically reads and decompresses the full response body without enforcing configured size limits. A malicious server can exploit this by serving an excessively compressed response, bypassing decompression bomb safeguards. This issue leads to high memory and processor consumption, resulting in a Denial of Service (DoS) on the client.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-409 - Improper Handling of Highly Compressed Data (Data Amplification)
