CVE-2026-44232 is a high-severity vulnerability in the Node. js library dssrf-js by HackingRepo. The vulnerability involves incomplete filtering of special elements related to IPv6 addresses, allowing every IPv6 category to bypass the is_url_safe check in versions prior to 1. 3. 0. This issue is classified under CWE-791. The vulnerability has a CVSS 4. 0 base score of 8. 7, indicating a high impact if exploited. A fix for this vulnerability was introduced in version 1.
AI Analysis
Technical Summary
The dssrf-js Node.js library prior to version 1.3.0 contains a vulnerability (CVE-2026-44232) due to incomplete filtering of IPv6 addresses in its is_url_safe function. This allows all IPv6 categories to bypass security checks intended to prevent SSRF attacks. The vulnerability is tracked as CWE-791 and has a high CVSS 4.0 score of 8.7. The issue is resolved in dssrf-js version 1.3.0.
Potential Impact
If exploited, this vulnerability could allow attackers to bypass SSRF defense mechanisms in dssrf-js by leveraging IPv6 addresses, potentially leading to server-side request forgery attacks. The high CVSS score reflects the network attack vector, low complexity, no privileges or user interaction required, but with high impact on confidentiality. No known exploits are reported in the wild.
Mitigation Recommendations
Upgrade dssrf-js to version 1.3.0 or later, where this vulnerability is fixed. Since the vendor advisory indicates the issue is resolved in this version, applying this update is the recommended remediation. There is no indication of alternative mitigations or temporary fixes.
