CVEs this fix closes

Priority	CVE	Title	CVSS	EPSS	Exploitation
High	CVE-2025-23166	Node.js 20 and 3 others: Uncaught Exception	7.5	0.0082	None reported
High	CVE-2025-23165	Node.js 20 and 1 other: Missing Release of Memory after Effective Lifetime	7.5	0.0056	None reported
High	CVE-2025-23167	A flaw in Node.js 20's HTTP parser allows improper termination of HTTP/1 headers using `\r\n\rX` instead of the required `\r\n\r\n`. This inconsistency enables request smuggling, allowing attackers to bypass proxy-based access controls and submit unauthorized requests. The issue was resolved by upgrading `llhttp` to version 9, which enforces correct header termination. Impact: * This vulnerability affects only Node.js 20.x users prior to the `llhttp` v9 upgrade.	7.5	0.0051	None reported
Routine	CVE-2025-47279	undici Denial of Service attack via bad certificate data	3.1	0.0034	None reported
