Insertion of Sensitive Information Into Sent Data vulnerability in ZealousWeb Accept Stripe Payments Using Contact Form 7 allows Retrieve Embedded Sensitive Data. This issue affects Accept Stripe Payments Using Contact Form 7: from n/a through 3.0.
AnalysisAI
Unauthenticated exposure of sensitive data in Accept Stripe Payments Using Contact Form 7 plugin up to version 3.0 sends embedded secrets (e.g., API keys) in network traffic, allowing remote attackers to retrieve that data. The vulnerability stems from insertion of sensitive information into sent data, with a CVSS 5.3 base score. No active exploitation or public proof-of-concept has been identified at this time, and the EPSS exploitation probability is very low (0.06%).
Technical ContextAI
The WordPress plugin uses Contact Form 7 to process Stripe payments and, due to CWE-201 (Insertion of Sensitive Information Into Sent Data), fails to remove sensitive credentials such as test or live API keys from outgoing requests or page responses. This may occur when the plugin constructs API calls or renders front-end code, inadvertently exposing secrets that can be captured by an intermediary or read from page source. The vulnerability affects the entire plugin up to version 3.0, as confirmed by both EUVD and Patchstack records.
RemediationAI
Upgrade the plugin to the latest version immediately; Patchstack advisory implies a fixed version (presumably 3.1 or later) exists. No specific workaround is provided. As a compensating control until patching, restrict network access to the WordPress instance (e.g., behind a VPN) or disable the Stripe payment feature if not essential-this will disrupt the payment workflow. Monitor the plugin’s GitHub/WordPress repository for exact patched version number.
