MITRE ATT&CK

2 techniques across 2 tactics: Collection, Discovery

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

No special conditions - the plugin's stored-submission export routine performs no authorization check, so remote unauthenticated exploitation works against default configurations of the Accept PayPal Payments using Contact Form 7 plugin in all versions before 4.0.7. The only practical limiters are that the target site must have this specific plugin installed and must have stored form submissions for any data to be disclosed; there is no user interaction, authentication, or non-default setting required.

Impact

Signals are moderate but one-sided. The NVD CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/C:L/I:N/A:N = 5.3) confirms a remotely reachable, unauthenticated, low-complexity information-disclosure flaw with no integrity or availability impact. No EPSS score, no CISA KEV listing, and no public POC were provided, so there is no evidence of active or at-scale exploitation at this time - exploitation status is 'no public exploit identified at time of analysis.' The one point of tension is the confidentiality rating: NVD scores C:L, but the description says the flaw dumps the complete personal data (name, email, telephone, postal address, message) and payment metadata of every form submitter, which is a bulk PII breach that many analysts would rate C:H - this drives my independent assessment higher (7.5). Net: this is a credible, low-friction data-exposure bug worth prompt patching for any site running the affected plugin, but absent EPSS/KEV/POC it is not an emergency on the scale of a mass-exploited RCE. The main unknown is real-world install footprint, which the provided data does not quantify.

Exploit ScenarioDerived

An unauthenticated attacker discovers a WordPress site running the vulnerable plugin and sends a request to its submission-export function, which performs no authorization check. The server returns a file containing the personal details and payment metadata of everyone who ever submitted the payment form. No public exploit code was provided, but given AV:N/AC:L/PR:N the request is trivial to craft and automate.

AnalysisAIv1 – Oct 10, 2026

Unauthenticated information disclosure in the WordPress plugin 'Accept PayPal Payments using Contact Form 7' (all versions before 4.0.7) allows any remote visitor to download the stored form submissions - name, email, telephone, postal address, message and associated payment metadata - of every person who submitted a payment form. The plugin's export routine performs no authorization check whatsoever, so exploitation requires no account, no user interaction and no non-default configuration; the only practical preconditions are that the plugin is installed and that at least one submission has been stored. Our independent assessment rates confidentiality impact as High (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) rather than the feed-supplied C:L, and no public exploit code or confirmed active exploitation has been identified at time of analysis; a vendor fix is available in version 4.0.7.

RemediationAI

Vendor-released patch: version 4.0.7 - upgrade the 'Accept PayPal Payments using Contact Form 7' plugin to 4.0.7 or later immediately, and verify the installed version via wp-cli ('wp plugin list') or the WordPress Plugins screen; details are in the WPScan advisory at https://wpscan.com/vulnerability/211d7613-a7e0-45f9-b262-66651aa4f535/. If the plugin cannot be patched promptly, deactivate and delete it (trade-off: payment form functionality is lost, but stored data remains in the database and is no longer servable by the vulnerable code); purge or archive existing stored submissions and payment metadata after export, since the vulnerability concerns data already at rest. Additional compensating controls - blocking or restricting access to the plugin's export/download handler at the web server or WAF, and adding authentication to any remaining export path - reduce exposure but are brittle because they depend on correctly enumerating every entry point the plugin registers, and they can break legitimate administrator exports. Because exploitation is unauthenticated and passive data retrieval leaves limited forensic traces, treat any period of unpatched exposure as a potential breach: review access logs for requests to plugin export endpoints and be prepared to notify affected submitters given the PII and payment metadata involved. No patch unavailability applies here; there is no need for purely mitigative measures on patched sites.

Technical ContextAI · show details

The vulnerable component is a WordPress plugin that extends Contact Form 7 to accept and process PayPal payments, persisting each submission together with payment metadata in the site's database. The root cause maps to CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor): the export/download routine that serves stored submissions lacks any capability or authorization verification - in WordPress terms, an endpoint reachable without a current_user_can() capability check (and typically without a nonce), so requests from unauthenticated visitors are served the same data an administrator would see. Because WordPress exposes such handlers through publicly reachable entry points (admin-ajax.php/admin-post.php style handlers or a direct download script), the missing check converts an administrative data-export feature into an open endpoint. The affected version range given by ENISA (EUVD-2026-96124) is 0 < 4.0.7; no CPE strings were supplied in the feeds, so product identification should be performed via WordPress plugin/theme inventory (WPScan, wp-cli plugin list) rather than CPE matching. The impact class is pure confidentiality loss - no integrity or availability effect - which is why the vector is S:U/I:N/A:N with the confidentiality metric the sole point of contention between the feed (C:L) and our assessment (C:H), the latter reflecting that wholesale PII and payment metadata of all submitters is disclosed.
