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-2026-106070](https://patchblox.com/security/data/cve/CVE-2026-106070.md) | Routine | Node.js and 17 others: Business Logic Errors | no-fix | ## Security fixes, newest first | Fix | Released | Fixed in | Priority | CVEs | Exploited | |---|---|---|---|---:|---:| | [Node.js 16 16.20.2](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.20.2.md) | Aug 8, 2023 | 16.20.2 | High | 3 | 0 | | [Node.js 16 16.20.1](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.20.1.md) | Jun 20, 2023 | 16.20.1 | High | 5 | 0 | | [Node.js 16 16.19.1](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.19.1.md) | Feb 16, 2023 | 16.19.1 | High | 4 | 0 | | [Node.js 16 16.18.1](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.18.1.md) | Nov 4, 2022 | 16.18.1 | High | 1 | 0 | | [Node.js 16 16.17.1](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.17.1.md) | Sep 23, 2022 | 16.17.1 | High | 4 | 0 | | [Node.js 16 16.16.0](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.16.0.md) | Jul 7, 2022 | 16.16.0 | High | 3 | 0 | | [Node.js 16 16.13.2](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.13.2.md) | Jan 10, 2022 | 16.13.2 | High | 4 | 0 | | [Node.js 16 16.11.1](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.11.1.md) | Oct 12, 2021 | 16.11.1 | High | 2 | 0 | | [Node.js 16 16.6.2](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.6.2.md) | Aug 11, 2021 | 16.6.2 | High | 4 | 0 | | [Node.js 16 16.6.0](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.6.0.md) | Jul 29, 2021 | 16.6.0 | High | 1 | 0 | | [Node.js 16 16.4.1](https://patchblox.com/security/data/fix/windows-app/openjs.nodejs.16-16.4.1.md) | Jul 1, 2021 | 16.4.1 | High | 2 | 0 | --- Data as of 2026-11-07T06:34:28Z UTC.
