CVE-2025-64269 identifies a missing authorization vulnerability in the EDGARROJAS WooCommerce PDF Invoice Builder plugin, specifically versions up to 1.2.150. This vulnerability arises from improperly configured access control mechanisms that fail to verify whether a user is authorized to perform certain actions within the plugin. As a result, an unauthenticated attacker can exploit this flaw by interacting with the plugin's interface or API endpoints that generate or manage PDF invoices, potentially accessing sensitive invoice data without proper permissions. The vulnerability has a CVSS 3.1 base score of 4.3, indicating medium severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact is limited to confidentiality (C:L), with no impact on integrity or availability. No known exploits are currently reported in the wild, and no official patches have been linked yet. The flaw primarily threatens the confidentiality of invoice data, which may include customer details, transaction amounts, and other sensitive business information. Since WooCommerce is widely used in e-commerce platforms, the plugin's vulnerability could expose sensitive financial documents if exploited. The vulnerability's exploitation does not require authentication but does require some form of user interaction, such as clicking a crafted link or visiting a malicious page. This increases the risk in environments where users may be tricked into interacting with malicious content. The vulnerability was reserved on 2025-10-29 and published on 2025-11-13, indicating recent discovery and disclosure.

For European organizations, the primary impact of CVE-2025-64269 is the potential unauthorized disclosure of sensitive invoice data, which can include customer personal information, transaction details, and pricing. This breach of confidentiality can lead to privacy violations under GDPR, reputational damage, and potential financial losses if sensitive business information is leaked. While the vulnerability does not affect data integrity or system availability, the exposure of confidential financial documents can facilitate further targeted attacks such as phishing or fraud. E-commerce businesses relying on WooCommerce with the vulnerable plugin are at risk, especially those processing large volumes of transactions or handling sensitive customer data. The medium severity rating reflects the limited scope of impact but acknowledges the risk posed by unauthorized data access. Since no authentication is required, attackers can exploit the vulnerability remotely, increasing the threat surface. The requirement for user interaction means social engineering or phishing could be used to trigger exploitation. Organizations failing to address this vulnerability may face compliance issues with European data protection regulations and increased risk of data breaches.

European organizations should immediately audit their WooCommerce installations to identify the presence and version of the EDGARROJAS WooCommerce PDF Invoice Builder plugin. Until an official patch is released, administrators should restrict access to the plugin's invoice generation and management features by implementing strict role-based access controls and limiting plugin usage to trusted users only. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin's endpoints. Educate users about phishing and social engineering risks to reduce the likelihood of user interaction exploitation. Monitor logs for unusual access patterns or attempts to access invoice-related resources without proper authorization. Consider temporarily disabling the plugin if it is not critical to operations or if mitigating controls cannot be enforced. Once a vendor patch becomes available, prioritize timely application of updates. Additionally, conduct regular security assessments and penetration testing focused on access control mechanisms within e-commerce platforms. Implement data encryption for stored invoices to reduce the impact of unauthorized access.
