Unauthenticated Broken Access Control in Secure Card Gateway for ePay Paycenter (Piraeus Bank) <= 1.0.32 versions.
AnalysisAI
Broken access control in the Secure Card Gateway for ePay Paycenter WordPress plugin (versions ≤ 1.0.32) enables remote unauthenticated attackers to bypass authorization checks and invoke privileged plugin operations without supplying any credential. Reported by Patchstack and classified as CWE-862 (Missing Authorization), the flaw carries a CVSS 3.1 score of 6.5 with a fully network-accessible, zero-privilege, zero-interaction attack vector. No active exploitation has been confirmed - this CVE does not appear in the CISA KEV catalog - and no public proof-of-concept code has been identified at time of analysis.
Technical ContextAI
The affected software is a WordPress plugin developed by webhosting4ugr (CPE: cpe:2.3:a:webhosting4ugr:secure_card_gateway_for_epay_paycenter_(piraeus_bank):*:*:*:*:*:*:*:*) that integrates WordPress-based e-commerce sites with Piraeus Bank's ePay Paycenter payment processing service. CWE-862 (Missing Authorization) indicates that one or more plugin-registered endpoints - most likely WordPress admin-ajax handlers or REST API routes - execute sensitive operations without verifying the caller's capability or role. In WordPress, this pattern commonly manifests as AJAX actions registered with wp_ajax_nopriv_ hooks, which are accessible to anonymous HTTP clients by design, and which lack the current_user_can() capability checks needed to restrict privileged operations. The CVSS vector AV:N/AC:L/PR:N/UI:N confirms the vulnerable endpoint is reachable over standard HTTP/HTTPS without any authentication credential, special network position, or victim interaction.
RemediationAI
Site administrators should update the Secure Card Gateway for ePay Paycenter plugin to a version beyond 1.0.32 immediately; the exact patched release version is not specified in the available intelligence and must be confirmed via the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/secure-card-gateway-for-epay-paycenter-piraeus-bank/vulnerability/wordpress-secure-card-gateway-for-epay-paycenter-piraeus-bank-plugin-1-0-32-broken-access-control-vulnerability or through the WordPress Plugin Repository. If an immediate update is not possible, a compensating control is to deactivate the plugin entirely until patching is feasible - this eliminates the exposed attack surface but will disable payment processing through the Piraeus Bank ePay Paycenter integration, which is a significant operational trade-off for any active merchant. Broad network-level blocking of WordPress admin-ajax endpoints is not a reliable substitute for patching, as wp_ajax_nopriv_ actions are a standard WordPress pattern and indiscriminate filtering risks breaking other legitimate plugin functionality.
