Red Hat Security Advisory: OpenShift Container Platform 4.20.27 bug fix and security update

Important

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by crafting a malicious Uniform Resource Identifier (URI) that contains percent-encoded authority delimiters. The fast-uri library incorrectly decodes these delimiters during normalization and then re-emits them as raw separators, which can change the URI's intended authority. This issue allows applications that perform host allowlist checks, redirect validation, or outbound request routing to be steered to a different authority than specified, potentially bypassing security controls.

CWE-140 - Improper Neutralization of Delimiters

A flaw was found in Axios. This vulnerability, a Prototype Pollution "Gadget" attack, allows an attacker to escalate any existing Object.prototype pollution in an application's dependency tree into a full Man-in-the-Middle (MITM) attack. This enables the attacker to intercept, read, and modify all HTTP traffic, including sensitive authentication credentials. The flaw occurs because the `config.proxy` setting is susceptible to prototype pollution, allowing an attacker to inject a malicious proxy server.

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