CVE-2025-62078 identifies a missing authorization vulnerability (CWE-862) in the Easy Upload Files During Checkout plugin developed by Fahad Mahmood, affecting versions up to 3.0.0. This vulnerability arises from incorrectly configured access control mechanisms that fail to properly verify whether a user has the necessary permissions to perform certain actions during the file upload process in the checkout workflow. Specifically, an attacker with some level of authenticated access (PR:L) can exploit this flaw remotely (AV:N) without requiring user interaction (UI:N) to bypass authorization checks and potentially modify or upload files that should be restricted. Although the vulnerability does not disclose sensitive information (C:N) nor impact system availability (A:N), it compromises data integrity (I:L) by allowing unauthorized modifications. The CVSS v3.1 base score is 4.3, reflecting a medium severity level. No patches or known exploits are currently available, indicating the vulnerability is newly disclosed and not yet actively exploited. The issue is particularly relevant for e-commerce platforms relying on this plugin to handle file uploads during checkout, where unauthorized file manipulation could lead to fraudulent transactions or data tampering. The vulnerability’s presence in a widely used plugin could have broad implications if exploited at scale.

For European organizations, especially those operating e-commerce platforms using the Easy Upload Files During Checkout plugin, this vulnerability poses a risk to transactional integrity. Unauthorized file uploads or modifications during checkout could lead to fraudulent orders, manipulation of order data, or injection of malicious files that may further compromise systems. While confidentiality and availability are not directly impacted, the integrity breach can undermine customer trust and lead to financial losses or regulatory scrutiny under GDPR if customer data is indirectly affected. The medium severity score suggests moderate risk, but the potential for exploitation by insiders or attackers with limited privileges means organizations must not overlook this issue. The lack of known exploits currently reduces immediate risk, but the vulnerability could be targeted once publicized. European businesses with high transaction volumes or those in regulated sectors should prioritize assessment and mitigation to prevent exploitation.

Organizations should immediately review and restrict user privileges to the minimum necessary, ensuring that only authorized roles can perform file uploads during checkout. Implement strict access control policies and monitor logs for unusual file upload activities or unauthorized access attempts. Employ web application firewalls (WAFs) with custom rules to detect and block anomalous requests targeting the vulnerable plugin endpoints. Since no patch is currently available, consider temporarily disabling the plugin or replacing it with a secure alternative if feasible. Conduct thorough security testing of the checkout process to identify any unauthorized access paths. Stay informed on vendor updates and apply patches promptly once released. Additionally, implement multi-factor authentication for administrative access and regularly audit user permissions to reduce the risk of privilege escalation that could facilitate exploitation.
