ac644e3→f8bbc73hypershift: Konnectivity proxy-server accepts agent connections without validating client certificates
CVE-2026-16242
More information
Details
A flaw was found in the Konnectivity proxy-server configuration for hosted control planes. The agent-facing listener was started without --cluster-ca-cert (and without token-based agent authentication), so client certificates were not validated. A remote attacker who can reach the Konnectivity cluster endpoint could connect as an unauthenticated agent, join the routing pool, and potentially proxy, inspect, modify, or drop control-plane-to-node traffic.

dompurify: DOMPurify: Cross-site scripting vulnerability allows code execution
CVE-2026-49978
More information
Details
A flaw was found in DOMPurify, a tool designed to sanitize HTML, MathML, and SVG to prevent cross-site scripting (XSS) attacks. When performing in-place sanitization, DOMPurify could fail to properly process content within shadow DOM elements attached to a .content. This oversight allows an attacker to embed malicious code, such as JavaScript, which could then execute when the sanitized template is used by an application, potentially leading to unauthorized actions or information disclosure.

js-yaml: js-yaml: Denial of Service via crafted YAML documents
CVE-2026-59869
More information
Details
A flaw was found in js-yaml, a JavaScript YAML parser and dumper. A remote attacker could exploit this vulnerability by providing a specially crafted YAML document containing a chain of mappings with merge keys. This could cause the parser to consume excessive CPU resources, leading to a Denial of Service (DoS) for the affected system.

tar: node-tar: Denial of Service via crafted gzip bomb
CVE-2026-59873
More information
Details
A flaw was found in node-tar, a tar archive manipulation library for Node.js. This vulnerability allows a remote attacker to craft a small gzip bomb, which, when processed, can lead to the exhaustion of disk space and CPU resources. This occurs because node-tar does not enforce strict limits on the total decompressed data, the number of entries, or the decompression ratio during extraction and parsing. The primary impact is a Denial of Service (DoS), making the affected system or application unavailable.
