CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N

Attack Vector: Network
Attack Complexity: Low
Privileges Required: None
User Interaction: None
Scope: Changed
Confidentiality: None
Integrity: Low
Availability: None

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: 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.

Detectable: 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 2026-10-26.

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. RBI should urgently implement strict authorization and verification controls on the signup API to ensure only legitimate users can create accounts, such as CAPTCHA, email or phone verification, and rate limiting. 2. Organizations using the RBI assistant platform should monitor account creation logs for unusual spikes or patterns indicative of automated or malicious signups. 3. Employ anomaly detection systems to flag suspicious user behaviors post-account creation, such as rapid order placements or unusual access times. 4. Restrict API access where possible using network segmentation or IP whitelisting to limit exposure. 5. Educate staff and customers about potential phishing or social engineering attempts stemming from unauthorized accounts. 6. Maintain up-to-date incident response plans to quickly address any abuse resulting from this vulnerability. 7. Engage with RBI for timely patch deployment and verify fixes through penetration testing. 8. Consider implementing multi-factor authentication (MFA) for sensitive operations within the platform to reduce the impact of unauthorized accounts.

Description

The Restaurant Brands International (RBI) assistant platform through 2025-09-06 has an "Anyone Can Join This Party" signup API that does not verify user account creation, allowing a remote unauthenticated attacker to create a user account.

Impact

For European organizations, the primary impact of CVE-2025-62642 lies in unauthorized account creation on the RBI assistant platform, which could lead to fraudulent orders, abuse of loyalty programs, or manipulation of user-generated data. While the vulnerability does not directly compromise confidentiality or availability, the integrity of user accounts and associated transactions is at risk. This could result in financial losses, reputational damage, and operational disruptions, especially for restaurant chains and partners relying on the platform for customer engagement and order management. Additionally, attackers might use created accounts as stepping stones for social engineering or phishing campaigns targeting employees or customers. The medium severity rating indicates a moderate but tangible risk that should not be overlooked, particularly in countries with high RBI market penetration or where digital restaurant services are critical. The absence of known exploits suggests a window for proactive mitigation, but organizations must act swiftly to prevent potential abuse.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
