CVE-2026-24580 identifies a missing authorization vulnerability in the Ecwid by Lightspeed Ecommerce Shopping Cart software, affecting versions up to and including 7.0.5. This vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict user permissions. As a result, an attacker with some level of authenticated access (PR:L in CVSS) can remotely exploit this flaw without requiring any user interaction (UI:N). The vulnerability primarily impacts confidentiality (C:L), allowing unauthorized access to information that should be protected, but does not compromise data integrity or system availability. The CVSS 3.1 base score of 4.3 reflects a medium severity, indicating a moderate risk level. No known public exploits or patches are currently documented, suggesting the vulnerability is newly disclosed or not yet widely exploited. The issue is significant for ecommerce platforms relying on Ecwid Shopping Cart, as unauthorized data access could expose sensitive customer or business information. The root cause is an access control misconfiguration, which is a common security weakness that can be mitigated by proper authorization checks and role-based access control enforcement. Given the remote network attack vector and absence of user interaction, attackers could automate exploitation if they have valid credentials or access to a compromised account. This vulnerability underscores the importance of secure configuration management in ecommerce software to protect sensitive transaction and customer data.

For European organizations using Ecwid Shopping Cart, this vulnerability poses a risk of unauthorized disclosure of sensitive ecommerce data, including customer information, order details, and possibly payment metadata. Such data exposure can lead to privacy violations under GDPR, reputational damage, and potential financial losses. Although the vulnerability does not allow data modification or service disruption, the confidentiality breach alone can have serious compliance and trust implications. European ecommerce businesses, especially SMEs relying on third-party shopping cart solutions like Ecwid, may be targeted by attackers seeking to harvest customer data for fraud or identity theft. The remote exploitability without user interaction increases the risk of automated attacks. Furthermore, given the interconnected nature of ecommerce ecosystems, unauthorized access could facilitate further lateral attacks or data leakage. Organizations may also face regulatory scrutiny if they fail to adequately protect customer data. The medium severity suggests that while the threat is not critical, it should not be ignored, especially in highly regulated European markets.

European organizations should immediately audit their Ecwid Shopping Cart configurations to verify and enforce strict access control policies, ensuring that only authorized roles have access to sensitive functions and data. Implement role-based access control (RBAC) with the principle of least privilege to minimize exposure. Monitor logs for unusual access patterns or privilege escalations related to the shopping cart system. If possible, upgrade Ecwid Shopping Cart to the latest version once a patch addressing CVE-2026-24580 is released. In the absence of an official patch, consider applying temporary compensating controls such as network segmentation, IP whitelisting, or multi-factor authentication (MFA) for administrative access to reduce exploitation risk. Conduct regular security assessments and penetration testing focused on access control mechanisms. Educate staff on the importance of secure credential management to prevent attackers from gaining the authenticated access required to exploit this vulnerability. Finally, maintain compliance with GDPR by promptly reporting any data breaches resulting from this vulnerability and reviewing data protection policies.
