Description
The Cryptocurrency Donation Box – Bitcoin & Crypto Donations plugin for WordPress is vulnerable to Stored Cross-Site Scripting via data_object Parameter in all versions up to, and including, 2.2.13 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by unauthenticated attackers because the cdbbc_payment_verify AJAX action is registered under wp_ajax_nopriv_ and its only authentication gate — a nonce check — is bypassable, as the cdbbc_donation_box nonce is publicly exposed to anonymous visitors via the wallets_data JavaScript object emitted by the [crypto-donation-box] shortcode.

AI Analysis

Impact

The Cryptocurrency Donation Box for WordPress is affected by a stored cross‑site scripting flaw caused by insufficient input sanitization and output escaping. An unauthenticated attacker can submit a payload through the data_object parameter that is written to the database and subsequently rendered in the plugin’s pages. When a user views the affected page, the malicious script runs in the victim’s browser.

Affected Systems

All releases of BlackWorks1’s Cryptocurrency Donation Box – Bitcoin & Crypto Donations plugin for WordPress up through version 2.2.13.

Risk and Exploitability

The vulnerability carries a CVSS score of 7.2, indicating moderate‑to‑high severity, while the EPSS score of less than 1% suggests low current exploitation likelihood. It is not listed in CISA’s KEV catalog. Because the cdbbc_payment_verify AJAX endpoint is registered with wp_ajax_nopriv_ and its sole authentication gate is a nonce that is publicly exposed, the flaw can be exploited purely by unauthenticated users.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update the Cryptocurrency Donation Box plugin to the latest version that contains the XSS fix (e.g., 2.2.14 or newer).
  • Add an explicit access control check to the cdbbc_payment_verify AJAX handler so that only users with appropriate capabilities can submit data, rather than relying solely on the public nonce.
  • Modify the shortcode that emits the cdbbc_donation_box nonce so that the JavaScript object is only rendered for authenticated users, preventing anonymous visitors from obtaining the nonce.
  • Configure a web application firewall or employ a security plugin to detect and block unauthorized script injection attempts against the AJAX endpoint.
