At a glance
CVE-2026-93885 is a high-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Cryptocurrency Donation Box WordPress plugin, affecting versions <= 2.2.13. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed October 2026, reported by Spy0x7.
Vulnerability Overview
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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Cryptocurrency Donation Box <= 2.2.13 takes no account at all. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. No fixed build of this plugin is recorded for Cryptocurrency Donation Box yet, so installs running <= 2.2.13 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
