Summary

Red Hat Security Advisory: Technical preview of the satellite/iop-vulnerability-frontend-rhel9 container image

Severity

Critical

Notes

Topic: A new satellite/iop-vulnerability-frontend-rhel9 container image is now available as a technical preview in the Red Hat container registry.

Details: Red Hat Lightspeed in Satellite analyzes system health and configuration by applying predefined rules to a small set of local data, such as installed packages, running services, and configuration settings.

CVE-2026-21441

urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP `Content-Encoding` header (e.g., `gzip`, `deflate`, `br`, or `zstd`). When using the streaming API, the library decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to drain the connection and decompress the content unnecessarily. This decompression occurred even before any read methods were called, and configured read limits did not restrict the amount of decompressed data. As a result, there was no safeguard against decompression bombs. A malicious server could exploit this to trigger excessive resource consumption on the client. Applications and libraries are affected when they stream content from untrusted sources by setting `preload_content=False` when they do not disable redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content of redirect responses when `preload_content=False`. If upgrading is not immediately possible, disable redirects by setting `redirect=False` for requests to untrusted source.

                          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)

Vendor Fix For Red Hat Lightspeed in Satellite installation see the Red Hat Satellite documentation. https://access.redhat.com/errata/RHSA-2026:8501

CVE-2026-25639

A denial of service flaw has been discovered in the Axios npm package. the mergeConfig function in axios crashes with a TypeError when processing configuration objects containing __proto__ as an own property. An attacker can trigger this by providing a malicious configuration object created via JSON.parse(), causing complete denial of service.

7.5 (High)


                        
                          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

CWE-1287 - Improper Validation of Specified Type of Input

Vendor Fix For Red Hat Lightspeed in Satellite installation see the Red Hat Satellite documentation. https://access.redhat.com/errata/RHSA-2026:8501

Workaround Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

CVE-2026-40175

A flaw was found in Axios, a promise-based HTTP client. This vulnerability, known as Prototype Pollution, can be exploited through a specific "Gadget" attack chain. This allows an attacker to escalate a Prototype Pollution vulnerability in a third-party dependency, potentially leading to remote code execution or a full cloud compromise, such as bypassing AWS IMDSv2.

9.0 (Critical)


                        
                          CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H

CWE-915 - Improperly Controlled Modification of Dynamically-Determined Object Attributes

          "value": "urllib3 is an HTTP client library for Python. urllib3\u0027s streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP `Content-Encoding` header (e.g., `gzip`, `deflate`, `br`, or `zstd`). When using the streaming API, the library decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to drain the connection and decompress the content unnecessarily. This decompression occurred even before any read methods were called, and configured read limits did not restrict the amount of decompressed data. As a result, there was no safeguard against decompression bombs. A malicious server could exploit this to trigger excessive resource consumption on the client. Applications and libraries are affected when they stream content from untrusted sources by setting `preload_content=False` when they do not disable redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content of redirect responses when `preload_content=False`. If upgrading is not immediately possible, disable redirects by setting `redirect=False` for requests to untrusted source."

CVE-2026-25639 (GCVE-0-2026-25639)

Vulnerability from cvelistv5 – Published: 2026-02-09 20:11 – Updated: 2026-02-18 17:16

Title

Axios affected by Denial of Service via __proto__ Key in mergeConfig

Summary

Axios is a promise based HTTP client for the browser and Node.js. Prior to versions 0.30.3 and 1.13.5, the mergeConfig function in axios crashes with a TypeError when processing configuration objects containing __proto__ as an own property. An attacker can trigger this by providing a malicious configuration object created via JSON.parse(), causing complete denial of service. This vulnerability is fixed in versions 0.30.3 and 1.13.5.

Severity ?

7.5 (High)

CVE-2026-40175 (GCVE-0-2026-40175)

Vulnerability from cvelistv5 – Published: 2026-04-10 19:23 – Updated: 2026-04-16 18:45

Title

Axios has Unrestricted Cloud Metadata Exfiltration via Header Injection Chain

Summary

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.0 and 0.3.1, the Axios library is vulnerable to a specific "Gadget" attack chain that allows Prototype Pollution in any third-party dependency to be escalated into Remote Code Execution (RCE) or Full Cloud Compromise (via AWS IMDSv2 bypass). This vulnerability is fixed in 1.15.0 and 0.3.1.
