Attackers can leverage nested percent-encoded host strings to bypass security boundary checks, leading to unauthenticated SSRF to internal network nodes and cloud metadata endpoints.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-174 / CWE-918\n- **Attack Vector**: Network (AV:N)\n- **CVSS v3.1 Score**: 7.5 (High)\n- **EPSS Score**: 0.00234\n- **Impact Type**: Integrity (SSRF / Host Bypass)\n- **Exploit Status**: poc\n- **CISA KEV Status**: Not Listed\n\n## Affected Systems\n\n- Node.js applications running fast-uri dependency packages < 2.4.5\n- Node.js applications running fast-uri dependency packages >= 3.1.2 and < 3.1.6\n- Node.js applications running fast-uri dependency packages >= 4.0.0 and < 4.1.3\n- **fast-uri**: >= 2.4.1 < 2.4.5 (Fixed in: `2.4.5`)\n- **fast-uri**: >= 3.1.2 < 3.1.6 (Fixed in: `3.1.6`)\n- **fast-uri**: >= 4.0.0 < 4.1.3 (Fixed in: `4.1.3`)\n\n## Mitigation\n\n- Upgrade the fast-uri package to patched versions 2.4.5, 3.1.6, or 4.1.3 depending on the respective dependency branch\n- Implement deep input validation to reject hostnames containing raw percent signs (%) prior to passing them to parsing and recomposition routines\n- Verify transitive dependencies (such as fastify and related plugins) to confirm no older versions of fast-uri are pulled into the project lockfile\n\n**Remediation Steps:**\n1. Identify the current installed version of fast-uri by inspecting package-lock.json or yarn.lock\n2. Run the upgrade command: npm install fast-uri@4.1.3 (or @3.1.6 / @2.4.5 depending on your major version pin)\n3. Re-generate package lockfiles and run npm audit to confirm the security advisory is resolved\n4. Deploy the updated application to staging environments and execute validation test scripts containing nested percent-encoded vectors to ensure functionality remains normal\n\n## References\n\n- [GitHub Security Advisory (GHSA-fph4-wmhf-6fwf)](https://github.com/fastify/fast-uri/security/advisories/GHSA-fph4-wmhf-6fwf)\n- [OpenJS Foundation Security Advisories](https://cna.openjsf.org/security-advisories.html)\n- [NVD Vulnerability Details - CVE-2026-75899](https://nvd.nist.gov/vuln/detail/CVE-2026-75899)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-75899) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-09-02T18:33:43.506559Z"} {"uuid": "df3b9443-53df-447d-ba4e-6d758c88a49b", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-75899", "type": "seen", "source": "https://gist.github.com/alon710/9abc2886db3d6d53b0a6da8c0c0bb7fc", "content": "# CVE-2026-75899: CVE-2026-75899: Double-Decoding Host Bypass and SSRF in fast-uri\n\n> **CVSS Score:** 7.5\n> **Published:** 2026-09-02\n> **Full Report:** https://cvereports.com/reports/CVE-2026-75899\n\n## Summary\nA double-decoding vulnerability in the fast-uri package allows unauthenticated remote attackers to bypass host-policy validation and conduct Server-Side Request Forgery (SSRF) attacks by submitting nested percent-encoded URI strings.\n\n## TL;DR\nThe fast-uri package redundantly decodes host components twice across the parsing and recomposition lifecycle.
