| [CVE-2018-12122](https://patchblox.com/security/data/cve/CVE-2018-12122.md) | High | Node.js 6 and 1 other: Uncontrolled Resource Consumption / Denial of Service | no-fix |
| [CVE-2019-5737](https://patchblox.com/security/data/cve/CVE-2019-5737.md) | High | Node.js 6 and 1 other: Uncontrolled Resource Consumption / Denial of Service | no-fix |
| [CVE-2020-8174](https://patchblox.com/security/data/cve/CVE-2020-8174.md) | High | Node.js 4 and 5 others: Memory Corruption - Generic (CWE-119) | no-fix |
| [CVE-2021-44531](https://patchblox.com/security/data/cve/CVE-2021-44531.md) | High | Node.js 14 and 8 others: Improper Certificate Validation (CWE-295) | no-fix |
| [CVE-2021-44532](https://patchblox.com/security/data/cve/CVE-2021-44532.md) | High | Node.js 14 and 8 others: Improper Following of a Certificate's Chain of Trust (CWE-296) | no-fix |
| [CVE-2021-44533](https://patchblox.com/security/data/cve/CVE-2021-44533.md) | High | Node.js 14 and 8 others: Improper Certificate Validation (CWE-295) | no-fix |
| [CVE-2026-106071](https://patchblox.com/security/data/cve/CVE-2026-106071.md) | High | A flaw in Node.js Permission Model filesystem enforcement can grant access to paths that do not match a wildcard `--allow-fs-read` or `--allow-fs-write` rule.  When the requested path is shorter than the prefix of a wildcard grant, the radix tree lookup stops comparing early and treats the path as a match. For example, `--allow-fs-read=/etc/passwd.*` also allows reading `/etc/passwd`. This requires the wildcard grant to sit directly under the root of the permission tree, for example when it is the only grant for that scope. This is a different root cause from CVE-2026-58043.  This vulnerability affects Node.js **26.x**. | no-fix |
| [CVE-2026-21637](https://patchblox.com/security/data/cve/CVE-2026-21637.md) | High | HackerOne: CVE-2026-21637 TLS PSK/ALPN Callback Exceptions Bypass Error Handlers | no-fix |
| [CVE-2026-21710](https://patchblox.com/security/data/cve/CVE-2026-21710.md) | High | A flaw in Node.js HTTP request handling causes an uncaught `TypeError` when a request is received with a header named `__proto__` and the application accesses `req.headersDistinct`.  When this occurs, `dest["__proto__"]` resolves to `Object.prototype` rather than `undefined`, causing `.push()` to be called on a non-array. This exception is thrown synchronously inside a property getter and cannot be intercepted by `error` event listeners, meaning it cannot be handled without wrapping every `req.headersDistinct` access in a `try/catch`.  * This vulnerability affects all Node.js HTTP servers on **20.x, 22.x, 24.x, and v25.x** | no-fix |
| [CVE-2026-21711](https://patchblox.com/security/data/cve/CVE-2026-21711.md) | High | Node.js 14 and 12 others: Improper Access Control | no-fix |
| [CVE-2026-21713](https://patchblox.com/security/data/cve/CVE-2026-21713.md) | High | Node.js 14 and 15 others: Observable Timing Discrepancy | no-fix |
| [CVE-2026-21714](https://patchblox.com/security/data/cve/CVE-2026-21714.md) | High | Node.js 14 and 15 others: Missing Release of Memory after Effective Lifetime | no-fix |
| [CVE-2026-21715](https://patchblox.com/security/data/cve/CVE-2026-21715.md) | High | Node.js 14 and 15 others: Incorrect Permission Assignment for Critical Resource | no-fix |
| [CVE-2026-21716](https://patchblox.com/security/data/cve/CVE-2026-21716.md) | High | Node.js 14 and 15 others: Missing Authorization | no-fix |
| [CVE-2026-21717](https://patchblox.com/security/data/cve/CVE-2026-21717.md) | High | A flaw in V8's string hashing mechanism causes integer-like strings to be hashed to their numeric value, making hash collisions trivially predictable. By crafting a request that causes many such collisions in V8's internal string table, an attacker can significantly degrade performance of the Node.js process.  The most common trigger is any endpoint that calls `JSON.parse()` on attacker-controlled input, as JSON parsing automatically internalizes short strings into the affected hash table.  This vulnerability affects **20.x, 22.x, 24.x, and 25.x**. | no-fix |
| [CVE-2018-12123](https://patchblox.com/security/data/cve/CVE-2018-12123.md) | Routine | Node.js 6 and 1 other: Misinterpretation of Input | no-fix |
| [CVE-2018-5407](https://patchblox.com/security/data/cve/CVE-2018-5407.md) | Routine | Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'. | no-fix |
| [CVE-2026-106070](https://patchblox.com/security/data/cve/CVE-2026-106070.md) | Routine | Node.js and 17 others: Business Logic Errors | no-fix |
