CVE-2026-45215: WP EasyPay Information Disclosure Flaw

CVE-2026-45215 Overview

CVE-2026-45215 is a sensitive data exposure vulnerability in the WP EasyPay WordPress plugin developed by Saad Iqbal. The flaw is classified under [CWE-201: Insertion of Sensitive Information Into Sent Data] and affects all versions of the plugin up to and including 4.3.0. An unauthenticated attacker can retrieve embedded sensitive data over the network without user interaction. The issue impacts the confidentiality of plugin-managed payment data on affected WordPress sites.

Critical Impact

Unauthenticated remote attackers can retrieve embedded sensitive information from WordPress sites running WP EasyPay 4.3.0 or earlier, exposing payment-related data to disclosure.

Affected Products

• Saad Iqbal WP EasyPay (wp-easy-pay) plugin for WordPress
• All versions from initial release through 4.3.0
• WordPress sites with the vulnerable plugin installed and active

Technical Details for CVE-2026-45215

Vulnerability Analysis

The vulnerability stems from the plugin embedding sensitive information into data sent to clients or external endpoints. An attacker reaches the affected functionality across the network without authentication or user interaction. Successful exploitation discloses payment-related or other embedded sensitive information processed by the plugin.

The weakness maps to [CWE-201], which covers cases where an application places confidential data in transmissions that are accessible to actors who should not have access. The EPSS model rates the probability of exploitation in the next 30 days as very low at the time of publication.

Root Cause

The plugin includes sensitive fields in responses or transmitted payloads without applying proper filtering or access checks. Because the data is embedded directly into output that reaches unauthenticated requesters, any visitor able to reach the affected endpoint can harvest it. The vendor advisory tracked by Patchstack confirms the data exposure pattern through version 4.3.0.

Attack Vector

The attack vector is network-based with low complexity and no privileges required. An attacker sends crafted or routine HTTP requests to the WordPress site hosting the vulnerable plugin and parses the response for sensitive fields. No victim interaction is needed to complete the attack. The vulnerability mechanism is documented in the Patchstack Vulnerability Report.

Detection Methods for CVE-2026-45215

Indicators of Compromise

• Unexpected outbound responses from WordPress endpoints associated with wp-easy-pay containing payment identifiers, customer fields, or configuration values
• Repeated unauthenticated requests to WP EasyPay plugin URLs (paths under /wp-content/plugins/wp-easy-pay/ or related AJAX/REST routes)
• Anomalous scraping behavior from a single source IP targeting checkout or payment pages

Detection Strategies

• Inventory all WordPress installations and flag instances running WP EasyPay version 4.3.0 or earlier
• Inspect HTTP responses from plugin endpoints for fields containing keys, tokens, or customer data that should not be client-visible
• Correlate web server access logs with WAF telemetry to identify enumeration of plugin endpoints

Monitoring Recommendations

• Log and retain full HTTP request and response metadata for the WordPress site, focusing on plugin paths
• Alert on bursts of unauthenticated requests to wp-easy-pay endpoints from non-customer IP ranges
• Review CDN and reverse proxy logs for response sizes or content types that deviate from baseline on payment pages

How to Mitigate CVE-2026-45215

Immediate Actions Required

• Identify every WordPress site running WP EasyPay and confirm the installed plugin version
• Upgrade WP EasyPay to a version later than 4.3.0 once the vendor releases a fixed build
• If no fixed version is available, deactivate and remove the plugin until a patch is published
• Rotate any API keys, payment processor credentials, or tokens that may have been embedded in responses

Patch Information

The vulnerability affects WP EasyPay through version 4.3.0. Refer to the Patchstack Vulnerability Report for the current fixed version once published by the vendor. Apply the update through the WordPress plugin updater or by replacing the plugin directory with the patched release.

Workarounds

• Restrict access to WP EasyPay endpoints using WAF rules that block unauthenticated requests to plugin paths from non-checkout flows
• Disable the plugin on environments that do not require active payment processing
• Place the WordPress site behind authentication or IP allowlisting during the remediation window where feasible

# Example WP-CLI commands to identify and disable the vulnerable plugin
wp plugin list --name=wp-easy-pay --fields=name,status,version
wp plugin deactivate wp-easy-pay
wp plugin update wp-easy-pay
