Exploitation Conditions

No special conditions are required beyond the target WordPress site having the Pay with Contact Form 7 plugin (version 1.0.4 or earlier) installed and active. The CVSS vector PR:N/UI:N/AC:L confirms exploitation requires no authentication, no user interaction, and no elevated complexity. The primary limiting factor is that the vulnerable site must have this specific plugin installed and network-accessible; WordPress installations with the plugin disabled or removed are not affected. Default WordPress configurations with this plugin active are vulnerable.

Impact

The CVSS 7.5 High rating is well-supported by the vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N): the attack requires no authentication, no special configuration, and no user interaction, and yields high confidentiality impact. No EPSS score is available in the provided data, and no CISA KEV listing exists, meaning active widespread exploitation is not confirmed - though the simplicity of the attack surface (unauthenticated GET/POST to a WordPress endpoint) implies a low skill threshold for any motivated attacker. No POC exploit has been identified at time of analysis. The scope is limited to WordPress sites running this specific payment-adjacent plugin, which constrains the total vulnerable population; nonetheless, even a mid-sized e-commerce operator in leszno processing customer payments through this form plugin should treat this as an urgent remediation priority given the complete absence of any authentication barrier protecting potentially sensitive financial or personal data.

Exploit ScenarioDerived

An unauthenticated attacker enumerates a target WordPress site, detects the presence of the Pay with Contact Form 7 plugin (e.g., via plugin-specific asset paths), then sends a crafted HTTP request to the vulnerable endpoint - requiring no credentials or cookies - and receives a response containing sensitive data such as payment transaction records or personal contact submissions. No public exploit code has been identified at time of analysis, but the low complexity of the attack vector makes manual exploitation straightforward.

AnalysisAIv1 – Aug 19, 2026

Unauthenticated sensitive data exposure in the CMSMinds Pay with Contact Form 7 WordPress plugin (versions through 1.0.4) allows remote, unauthenticated attackers to retrieve sensitive information - likely payment-related or personal contact data - without any credentials or user interaction. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) confirms a fully network-accessible attack path requiring zero privileges, yielding high confidentiality impact. No public exploit or CISA KEV listing has been identified at time of analysis.

RemediationAI

The primary remediation is to update the Pay with Contact Form 7 plugin to a version beyond 1.0.4; however, the available reference data does not specify an exact patched version number - administrators should consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/pay-with-contact-form-7/vulnerability/wordpress-pay-with-contact-form-7-plugin-1-0-4-sensitive-data-exposure-vulnerability and the WordPress plugin repository for the latest release. If no patched version is yet available, the immediate compensating control is to deactivate and remove the plugin entirely, which eliminates the exposed endpoint. A secondary mitigation is to restrict access to the WordPress installation's sensitive endpoints using server-level access controls (e.g., Apache/nginx rules blocking unauthenticated access to specific plugin REST routes or admin-ajax handlers), though this requires identifying the exact vulnerable endpoint and may affect legitimate plugin functionality. Note: no patch version has been independently confirmed from the available input data.

Technical ContextAI · show details

The affected product is the 'Pay with Contact Form 7' plugin by CMSMinds for WordPress (CPE: cpe:2.3:a:cmsminds:pay_with_contact_form_7:*:*:*:*:*:*:*:*), which extends the popular Contact Form 7 plugin to support payment collection directly within forms. CWE-201 ('Insertion of Sensitive Information Into Sent Data') indicates the root cause is the plugin inadvertently including sensitive data - such as payment credentials, transaction details, or personally identifiable contact information - in an HTTP response or API output that is accessible without authentication. This class of flaw typically arises when an endpoint intended for administrative or internal use lacks proper access controls, or when debug/verbose output containing sensitive fields is exposed to unauthenticated callers.

Unauthenticated Sensitive Data Exposure in Pay with Contact Form 7 <= 1.0.4 versions.

Executive ViewAI

Why It Matters

The CMSMinds Pay with Contact Form 7 WordPress plugin (versions through 1.0.4) permits unauthenticated remote attackers to access payment and customer contact data without credentials, creating direct exposure of sensitive financial records. Any organization running affected plugin versions exposes customer data to unauthorized disclosure, triggering potential PCI-DSS violations and reputational harm. Immediate remediation is required.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: (1) immediately disable/remove the plugin from all WordPress installations; (2) deploy WAF rules to block HTTP requests to vulnerable payment data endpoints; (3) restrict network access to WordPress administrative interfaces and payment information storage; (4) enable comprehensive database query logging and alerting on payment data access; (5) contact CMSMinds vendor requesting urgent security update timeline; (6) prepare customer notification and incident response procedures.
