A flaw was found in Lodash. An attacker can exploit a prototype pollution vulnerability in the `_.unset` and `_.omit` functions by bypassing a security check. This bypass is achieved by providing array-wrapped path segments, which allows for the deletion of properties from built-in JavaScript prototypes such as `Object.prototype`. This could lead to unexpected application behavior or denial of service.

Threats
Impact
Moderate
A flaw was found in the brace-expansion library. This vulnerability allows an attacker to cause a Denial of Service (DoS) by providing a large numeric range for expansion. The library allocates excessive memory to generate all intermediate elements before applying the maximum limit, leading to high memory consumption and potential application crashes. This can impact the availability of systems using the library.

Threats
Impact
Moderate
A flaw was found in Node.js. When proxy credentials are embedded in a proxy URL, an issue in the proxy tunnel error handling can lead to the exposure of these credentials. This information disclosure vulnerability allows an attacker to potentially capture sensitive proxy credentials through logs, diagnostics, or other error-consuming mechanisms.

Threats
Impact
Moderate
A flaw was found in Node.js. This flaw involves a mismatch in how Node.js handles TLS (Transport Layer Security) hostnames and unicode dot separators during authentication. This mismatch can lead to a wildcard-depth authentication bypass. An attacker could exploit this to bypass intended security boundaries, potentially leading to unauthorized access and confidentiality impact.

A flaw was found in js-yaml, a JavaScript YAML parser and dumper. When merge keys are enabled, a remote attacker could exploit this vulnerability by crafting a YAML document where a chain of mappings uses merge keys, each merging the previous one. This can lead to a significant increase in CPU time required to parse the document, resulting in a Denial of Service (DoS) for the affected system.
