Exposure of Sensitive System Information to an Unauthorized Control Sphere vulnerability in o2oe E-Invoice App Malaysia einvoiceapp-malaysia allows Retrieve Embedded Sensitive Data.This issue affects E-Invoice App Malaysia: from n/a through <= 1.3.0.
AnalysisAI
Unauthorized remote attackers can retrieve embedded sensitive system information from o2oe E-Invoice App Malaysia plugin versions 1.3.0 and earlier without authentication (CVSS:3.1 AV:N/AC:L/PR:N). The vulnerability exposes confidential data through information disclosure, with EPSS exploitation probability at 0.05% (14th percentile). No public exploit identified at time of analysis, though the low attack complexity and unauthenticated attack vector make exploitation straightforward for adversaries with network access to vulnerable WordPress installations.
Technical ContextAI
This vulnerability stems from CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere), where the E-Invoice App Malaysia WordPress plugin fails to properly restrict access to sensitive system information embedded within the application. The plugin, designed for Malaysian e-invoicing compliance, likely exposes configuration data, API credentials, database connection strings, or other sensitive parameters through publicly accessible endpoints or insufficiently protected resources. The CVSS vector indicates network-accessible exploitation with low complexity, suggesting the sensitive data may be retrievable through direct HTTP requests to predictable URIs, exposed API endpoints, or improperly secured configuration files within the WordPress plugin directory structure. WordPress plugins commonly suffer from information disclosure when developers embed credentials or system details in JavaScript files, expose debug endpoints, or fail to implement proper access controls on administrative interfaces.
Affected ProductsAI
The vulnerability affects o2oe E-Invoice App Malaysia WordPress plugin in all versions up to and including version 1.3.0. This is a specialized plugin for Malaysian e-invoicing compliance used primarily by Malaysian businesses integrating with local tax authority systems. The vulnerability disclosure from Patchstack ([email protected]) references version 1.1.0 specifically in their database entry, though the CVE scope extends through version 1.3.0, indicating the flaw persists across multiple releases. Affected installations are WordPress sites with the einvoiceapp-malaysia plugin actively installed and accessible via network interfaces.

RemediationAI
Users should immediately upgrade to E-Invoice App Malaysia plugin version 1.3.1 or later if available from the vendor o2oe. Verify patch availability through the WordPress plugin repository or directly from the vendor before deployment. As an interim workaround pending patch deployment, administrators should implement network-level access controls restricting plugin endpoints to authorized IP addresses only, deploy web application firewall rules blocking unauthorized access to sensitive plugin paths (typically wp-content/plugins/einvoiceapp-malaysia/*), and audit exposed configuration files for embedded credentials that should be rotated immediately. Review WordPress access logs for suspicious requests targeting the plugin directory to identify potential reconnaissance or exploitation attempts. After patching, conduct a security review to verify previously exposed sensitive data (API keys, database credentials, integration tokens) and rotate all potentially compromised credentials as a precautionary measure.
