Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

CVE published 16 Sep 2025
Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Immediate auditing of all Node.js applications and dependencies to identify usage of the 'ip' package (node-ip) versions up to 2.0.1. 2. Where possible, upgrade to a patched or newer version of the package once available from the vendor or maintainers. 3. Implement strict input validation and sanitization for IP address inputs, ensuring that special IP addresses like 0.0.0.0 and localhost are handled securely and not treated as publicly routable. 4. Employ network segmentation and firewall rules to restrict server-side requests from application servers to only necessary internal services, minimizing the attack surface for SSRF. 5. Monitor application logs for unusual outbound requests, especially those targeting localhost or internal IP ranges, to detect potential exploitation attempts. 6. Consider using runtime application self-protection (RASP) or web application firewalls (WAFs) that can detect and block SSRF patterns. 7. Educate development teams about the risks of SSRF and the importance of proper IP address handling in code.

Description

The ip (aka node-ip) package through 2.0.1 (in NPM) might allow SSRF because the IP address value 0 is improperly categorized as globally routable via isPublic. NOTE: this issue exists because of an incomplete fix for CVE-2024-29415. NOTE: in current versions of several applications, connection attempts to the IP address 0 (interpreted as 0.0.0.0) are blocked with error messages such as net::ERR_ADDRESS_INVALID. However, in some situations that depend on both application version and operating system, connection attempts to 0 and 0.0.0.0 are considered connection attempts to 127.0.0.1 (and, for this reason, a false value of isPublic would be preferable).

Impact

For European organizations, the impact of this SSRF vulnerability depends largely on the deployment of the 'ip' package within their software stacks, particularly in Node.js applications that process or validate IP addresses. Exploitation could allow attackers to perform unauthorized internal network scans or access internal services that are otherwise protected, potentially leading to information disclosure or indirect integrity compromises. While the vulnerability itself is low severity, it could serve as a pivot point in multi-stage attacks targeting internal infrastructure or sensitive services, especially in sectors with critical internal networks such as finance, healthcare, and government. Given the complexity and environment-specific nature of the vulnerability, exploitation may be limited but should not be disregarded. European organizations with Node.js environments that incorporate this package should be vigilant, as internal network architectures and regulatory requirements (e.g., GDPR) heighten the importance of preventing unauthorized internal access.
