CVE-2025-62078 is classified under CWE-862, indicating a Missing Authorization vulnerability in the Easy Upload Files During Checkout plugin by Fahad Mahmood. This plugin facilitates file uploads during the checkout process in e-commerce platforms. The vulnerability arises from incorrectly configured access control security levels, allowing users with limited privileges (PR:L) to perform unauthorized actions that should be restricted. The attack vector is network-based (AV:N), requiring no user interaction (UI:N), and the scope remains unchanged (S:U). The impact is limited to integrity (I:L), with no confidentiality or availability impact. The vulnerability affects all versions up to 3.0.0, though specific affected versions are not detailed. No patches or known exploits are currently available, suggesting the vulnerability is newly disclosed. The flaw could allow an attacker to manipulate uploaded files or related checkout data, potentially leading to fraudulent transactions or data tampering. Given the nature of e-commerce checkout processes, such unauthorized modifications could undermine transaction integrity and customer trust. The vulnerability's medium severity reflects its limited impact and the requirement for some level of privilege to exploit.

For European organizations, particularly those operating e-commerce platforms using the Easy Upload Files During Checkout plugin, this vulnerability poses a risk to transaction integrity. Unauthorized modification of uploaded files or checkout data could lead to fraudulent orders, financial discrepancies, or reputational damage. While confidentiality and availability are not directly impacted, the integrity compromise could affect compliance with data protection regulations such as GDPR, especially if transaction records are altered. The risk is heightened in sectors with high transaction volumes or sensitive customer data. Additionally, organizations lacking robust internal access controls or monitoring may be more vulnerable to exploitation. The absence of known exploits provides a window for proactive mitigation, but the medium severity rating suggests prioritization alongside other critical vulnerabilities. The impact on supply chain trust and customer confidence in European markets could be significant if exploited at scale.

1. Immediately review and tighten access control configurations within the Easy Upload Files During Checkout plugin to ensure that only authorized roles can perform file uploads and related actions during checkout. 2. Implement strict role-based access controls (RBAC) at the application and platform level to limit privileges to the minimum necessary. 3. Monitor and audit file upload activities and checkout transactions for unusual or unauthorized modifications. 4. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin's upload functionality. 5. Segregate duties among users to prevent privilege escalation or misuse of upload capabilities. 6. Until an official patch is released, consider disabling the plugin or restricting its use to trusted users only. 7. Keep abreast of vendor advisories and apply patches promptly once available. 8. Conduct penetration testing focusing on access control weaknesses in the checkout process to identify and remediate similar issues. 9. Educate development and operations teams about secure configuration practices for third-party plugins.
