CVE-2026-2658 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the newbee-mall e-commerce platform developed by newbee-ltd. The vulnerability affects multiple endpoints within the application, allowing an attacker to craft malicious requests that, when executed by an authenticated user, cause the user’s browser to perform unintended actions on the vulnerable server. The vulnerability does not require the attacker to have any privileges or prior authentication, but it does require the victim to interact with a malicious link or webpage (user interaction). The CVSS 4.0 base score is 5.3, reflecting medium severity, with an attack vector of network, low attack complexity, no privileges required, and user interaction necessary. The impact primarily affects integrity and partially availability, as unauthorized state changes could disrupt normal operations or manipulate data. The product follows a rolling release model, complicating version tracking and patch management. The vendor has been notified but has not yet responded or released a fix. No known exploits are currently active in the wild, but public exploit information exists, increasing the risk of future exploitation. This vulnerability is particularly concerning for e-commerce environments where unauthorized transactions or configuration changes could have financial and reputational consequences.

For European organizations, especially those operating e-commerce platforms or using newbee-mall, this vulnerability poses a risk of unauthorized transactions, data manipulation, or configuration changes initiated by attackers via CSRF attacks. Such unauthorized actions could lead to financial losses, customer trust erosion, and potential regulatory compliance issues under GDPR if personal data integrity is compromised. The medium severity indicates moderate risk, but the public availability of exploit details increases the urgency for mitigation. Disruption of service or fraudulent activities could impact business continuity and brand reputation. Organizations relying on newbee-mall should consider the threat in their risk assessments and incident response planning. The rolling release nature of the product may complicate patch deployment, requiring vigilant version control and update monitoring.

1. Implement CSRF tokens on all state-changing endpoints to ensure requests are legitimate and originate from authenticated users. 2. Enforce SameSite cookie attributes (preferably 'Strict' or 'Lax') to limit cross-origin requests carrying authentication cookies. 3. Employ user interaction validation mechanisms such as CAPTCHA or multi-factor authentication for sensitive operations. 4. Monitor and log unusual or unexpected state-changing requests to detect potential exploitation attempts. 5. Restrict HTTP methods to only those necessary (e.g., POST for state changes) and validate the Origin and Referer headers to confirm request legitimacy. 6. Maintain an up-to-date inventory of newbee-mall versions in use and subscribe to vendor or community advisories for patch releases. 7. Educate users about phishing and social engineering risks to reduce the likelihood of interaction with malicious links. 8. Consider deploying Web Application Firewalls (WAFs) with rules targeting CSRF attack patterns to provide an additional layer of defense.
