AI Analysis
Technical Summary
CVE-2026-3177 describes a vulnerability in the Charitable – Donation Plugin for WordPress (versions up to 1.8.9.7) where the plugin fails to perform cryptographic verification of incoming Stripe webhook events. This insufficient verification (CWE-345) allows attackers to forge payment_intent.succeeded webhook payloads, causing the system to incorrectly mark pending donations as completed without receiving real payments. The vulnerability has a CVSS 3.1 base score of 5.3, indicating a medium severity risk. No vendor-provided patch or official remediation level is documented, and the plugin is not a cloud service, so remediation depends on the vendor releasing an update.
Potential Impact
An attacker can exploit this vulnerability to forge Stripe webhook events, specifically payment_intent.succeeded, which results in the plugin marking donations as completed without actual payment. This can lead to financial discrepancies and potential loss of funds for organizations relying on the plugin for donation processing. There is no indication of confidentiality or availability impact, only integrity is affected.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling Stripe webhook processing or implementing additional verification mechanisms outside the plugin to validate webhook authenticity. Monitor official vendor channels for updates and apply patches promptly once available.
