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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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 2026-10-25.

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

To mitigate CVE-2024-9671, organizations should first check for and apply any official patches or updates released by the 3Scale vendor addressing this authorization flaw. In the absence of immediate patches, implement strict access controls at the web server or API gateway level to restrict access to invoice URLs only to authenticated and authorized users. Employ URL randomization or tokenization to make invoice URLs difficult to guess. Monitor access logs for unusual or unauthorized access attempts to invoice endpoints. Conduct regular security reviews of API endpoints to ensure proper authorization checks are in place. Additionally, consider encrypting sensitive invoice data at rest and in transit to reduce the impact of unauthorized access. Educate developers and administrators about the importance of securing sensitive resources and promptly reporting suspicious activity.

Description

A vulnerability was found in 3Scale. There is no auth mechanism to see a PDF invoice of a Developer user if the URL is known. Anyone can see the invoice if the URL is known or guessed.

Impact

The primary impact of CVE-2024-9671 is the unauthorized disclosure of sensitive billing information contained in Developer user PDF invoices. This confidentiality breach could lead to privacy violations, exposure of financial data, and potential reputational damage for affected organizations. Attackers could use the information for targeted phishing or social engineering attacks. Although the vulnerability does not affect data integrity or system availability, the exposure of private invoice data can have regulatory compliance implications, especially in jurisdictions with strict data protection laws. Organizations worldwide using vulnerable 3Scale versions may face increased risk of data leaks, particularly those with large developer ecosystems or sensitive billing information. The ease of exploitation without authentication increases the threat level, especially if invoice URLs follow predictable patterns that can be guessed or enumerated.

Summary

CVE-2024-9671 is a vulnerability identified in the 3Scale API management platform, specifically affecting versions 2.13.0 and 2.14.0. The issue arises from a missing authorization control on the endpoint serving PDF invoices for Developer users. This means that anyone who knows or can guess the URL of a Developer user's invoice can access the PDF document without any authentication or authorization checks. The vulnerability does not require any privileges or user interaction, making it relatively easy to exploit if the URL is discovered. The exposed invoices may contain sensitive billing information, leading to a confidentiality breach. However, the vulnerability does not allow modification of data or disruption of service, so integrity and availability remain unaffected. The CVSS v3.1 base score is 5.3, reflecting a medium severity due to the ease of access but limited impact scope. No public exploits have been reported yet, but the risk remains significant for organizations relying on these 3Scale versions for API management and billing. The lack of patch links suggests that users should monitor vendor advisories for updates or apply compensating controls immediately.
