CVE-2026-54722: CWE-76: Improper Neutralization of Equivalent Special Elements in HackingRepo dssrf-js
CVE-2026-54722 is a high-severity vulnerability in the dssrf-js Node.js library prior to version 1.0.4. The issue involves improper neutralization of special elements in URL processing, specifically the '@' userinfo delimiter. This flaw allows an attacker to bypass internal IP validation checks, potentially causing a client to access internal services via crafted URLs. The vulnerability is fixed in version 1.0.4.
AI Analysis
Technical Summary
The dssrf-js library provides SSRF defense utilities for Node.js. Before version 1.0.4, the function is_url_safe in src/helpers.ts removes the '@' symbol from URLs before parsing them with the URL constructor. This removal allows attacker-controlled URLs to bypass internal IP validation, enabling Server-Side Request Forgery (SSRF) attacks that reach internal services. The vulnerability is identified as CWE-76 (Improper Neutralization of Equivalent Special Elements). The issue is resolved in dssrf-js version 1.0.4.
Potential Impact
An attacker can craft URLs that bypass internal IP validation checks, potentially causing the client application to make unauthorized requests to internal services. This could lead to information disclosure or other impacts related to SSRF attacks. The CVSS 4.0 score is 8.7 (high), indicating a significant risk without requiring privileges or user interaction.
Mitigation Recommendations
Upgrade dssrf-js to version 1.0.4 or later, where this vulnerability is fixed. No other mitigation is specified or required as the fix addresses the root cause.
