CVE-2026-28213 is a critical vulnerability affecting EverShop, a TypeScript-first eCommerce platform. This vulnerability exists in the "Forgot Password" functionality where the API response reveals the password reset token when a target email address is specified. As a result, an attacker can take control of the associated account. The vulnerability is addressed in version 2.1.1, which organizations should upgrade to in order to secure their systems.
With a CVSS score of 9.8, this vulnerability is categorized as critical, indicating a significant risk to organizations that utilize EverShop. The attack vector is network-based, requiring no user interaction or privileges, thus making it easy for potential attackers to exploit. Organizations using affected versions should prioritize patching to prevent unauthorized access to user accounts.
The urgency for defenders is underscored by the potential for account takeover, which can lead to further exploitation of sensitive user data. Organizations should prioritize patching immediately.
No known public exploits exist at this time, but the nature of the vulnerability makes it a high-priority target for attackers. The risk to organizations includes not only loss of sensitive data but also reputational damage if exploits are successful.
Vulnerability Details
The official description details that EverShop versions prior to 2.1.1 have a flaw in the password reset functionality, exposing critical reset tokens to potential attackers. The vulnerability is classified under CWE-200 (Information Exposure) and CWE-640 (Weak Password Recovery Mechanism for Forgotten Password).
The CVSS score of 9.8 indicates the vulnerability's severity, highlighting the potential impacts on confidentiality, integrity, and availability. Organizations should assess their current version and upgrade to 2.1.1 or later as soon as possible.
Technical Analysis
The root cause of this vulnerability lies in the misconfiguration of the API response, which inadvertently reveals sensitive information. The attack vector is network-based, allowing remote attackers to exploit this flaw without needing physical access to the server.
The attack complexity is low, as no advanced skills are required to exploit the vulnerability. There are no privileges required for the attack, and user interaction is not needed, making it particularly dangerous.
The confidentiality impact is high, as sensitive user information could be exposed. Additionally, the integrity and availability impacts are also high, as attackers could potentially manipulate accounts after gaining access.
Risk & Impact Analysis
The real-world risk of this vulnerability is significant. Organizations that fail to patch could suffer from unauthorized account access, leading to data breaches and loss of customer trust. The potential blast radius includes all users who utilize the affected feature, making the vulnerability critical to address.
Given the CVSS score and the nature of the vulnerability, organizations should assess the urgency of their response. Immediate action is warranted to prevent potential exploitation and protect user accounts.
