| CVE | Priority | Title | CVSS | EPSS | Exploitation |
|---|---|---|---:|---:|---|
| [CVE-2025-23166](https://patchblox.com/security/data/cve/CVE-2025-23166.md) | High | Node.js 20 and 3 others: Uncaught Exception | 7.5 | 0.0082 |  |

| [CVE-2025-23167](https://patchblox.com/security/data/cve/CVE-2025-23167.md) | High | 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 |  |
