CVE-2025-67942 identifies a Missing Authorization vulnerability in the Peach Payments Gateway plugin for WordPress-based e-commerce platforms, specifically versions up to and including 3.3.6. The vulnerability arises from incorrectly configured access control mechanisms, allowing unauthenticated remote attackers to bypass authorization checks. This can lead to unauthorized access to certain functionalities or data within the payment gateway plugin, potentially exposing sensitive information or enabling limited manipulation of payment processes. The CVSS v3.1 base score is 6.5, reflecting a medium severity level, with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and low impact on confidentiality and integrity (C:L/I:L) but no impact on availability (A:N). No known exploits have been reported in the wild yet, and no patches are currently linked, suggesting that vendors and users should remain vigilant. The vulnerability affects the confidentiality and integrity of payment data but does not disrupt service availability. Given the nature of payment gateways, unauthorized access could lead to exposure of transaction details or manipulation of payment workflows, posing financial and reputational risks to affected organizations.

For European organizations, this vulnerability could lead to unauthorized access to payment transaction data or partial manipulation of payment processes, potentially resulting in data breaches, financial fraud, or loss of customer trust. E-commerce businesses relying on the Peach Payments Gateway may face regulatory scrutiny under GDPR if personal or payment data is exposed. The medium severity indicates that while the impact is not catastrophic, it is significant enough to warrant immediate attention, especially for organizations processing large volumes of transactions. The lack of required privileges or user interaction means attackers can exploit this remotely and anonymously, increasing the risk of widespread exploitation if left unmitigated. This could disrupt business operations indirectly through reputational damage and compliance penalties. The impact is particularly critical for sectors with high transaction volumes such as retail, travel, and digital services within Europe.

Organizations should monitor Peach Payments Gateway vendor communications closely for official patches addressing CVE-2025-67942 and apply them immediately upon release. In the interim, conduct a thorough audit of access control configurations within the payment gateway plugin to identify and remediate any misconfigurations. Restrict network access to the payment gateway administration interfaces using IP whitelisting or VPNs to limit exposure. Implement enhanced logging and monitoring to detect unusual access patterns or unauthorized attempts to interact with the payment gateway. Consider deploying web application firewalls (WAFs) with custom rules to block suspicious requests targeting the plugin endpoints. Educate IT and security teams about this vulnerability to ensure rapid response capabilities. Additionally, review and reinforce overall WordPress and WooCommerce security best practices, including timely updates, principle of least privilege for user roles, and regular security assessments.
