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.

CVE-2026-59869

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.
