CVE-2026-6798 Overview
CVE-2026-6798 affects the 2Download Connector for 2DL Hosted Checkout plugin for WordPress through version 0.1.5. The plugin fails to verify whether a user is authorized to perform certain actions, exposing customer subscription data to unauthenticated attackers. Affected data includes subscription status, product names, order IDs, purchase dates, and expiry dates. The flaw is categorized as a Missing Authorization weakness [CWE-862] and is exploitable over the network without user interaction.
Critical Impact
Unauthenticated remote attackers can retrieve arbitrary customers' subscription records from affected WordPress sites, leading to confidentiality loss for any customer using the plugin.
Affected Products
- 2Download Connector for 2DL Hosted Checkout plugin for WordPress
- All versions up to and including 0.1.5
- WordPress sites using the plugin's shortcode-driven subscription views

Technical Details for CVE-2026-6798
Vulnerability Analysis
The vulnerability is a Broken Access Control issue in the plugin's shortcode handlers. Code paths in src/Shortcodes/Shortcodes.php return subscription information without enforcing that the requester owns the data being retrieved. An unauthenticated visitor can craft requests against the affected shortcode endpoints and receive subscription records belonging to other customers. The exposed fields include subscription status, product names, order identifiers, purchase dates, and expiry dates, which together enable customer enumeration and targeted follow-on attacks such as phishing.
Root Cause
The root cause is missing authorization logic [CWE-862]. The plugin assumes that any caller invoking the affected shortcode functions is entitled to view the returned subscription data. There is no capability check, ownership check, or session-binding validation prior to query execution. Reviewers can verify the unprotected handlers in the trunk and tagged 0.1.5 sources at lines 1278, 1767, and 1776 of Shortcodes.php.
Attack Vector
The attack vector is network-based and requires no authentication, no privileges, and no user interaction. An attacker issues HTTP requests against the WordPress site that trigger the vulnerable shortcode logic. The response discloses customer subscription records. Because exploitation requires only standard web requests, it is suitable for automated scraping and bulk data harvesting from publicly reachable WordPress instances running the plugin.
No public proof-of-concept exploit is currently listed for this issue. See the Wordfence Vulnerability Report and the WordPress Plugin Code Reference for technical details.
Detection Methods for CVE-2026-6798
Indicators of Compromise
- Unauthenticated HTTP requests targeting WordPress pages that render 2Download Connector shortcodes, especially in bursts from a single source IP.
- Web server access logs showing successful 200 OK responses to subscription-related shortcode endpoints from clients with no authenticated session cookie.
- Anomalous spikes in outbound response sizes from pages embedding the plugin's subscription shortcodes.
Detection Strategies
- Inspect WordPress access logs for repeated requests to URLs containing pages where the plugin's shortcodes are embedded.
- Correlate unauthenticated request volume with subscription-record response sizes to flag scraping behavior.
- Use a web application firewall in monitor mode to baseline normal traffic to subscription pages, then alert on deviations.
Monitoring Recommendations
- Track HTTP request rates per source IP against pages hosting the 2Download Connector shortcodes.
- Monitor changes to the plugin version and to src/Shortcodes/Shortcodes.php for unexpected modifications.
- Alert on enumeration patterns such as sequential order ID or customer ID parameters in request strings.
How to Mitigate CVE-2026-6798
Immediate Actions Required
- Update the 2Download Connector for 2DL Hosted Checkout plugin to a version newer than 0.1.5 once the vendor publishes a fixed release.
- If no fixed version is available, deactivate and remove the plugin from production WordPress sites.
- Review web server logs for evidence of unauthenticated access to subscription shortcode pages and notify affected customers if disclosure is confirmed.
Patch Information
A plugin changeset is available at the WordPress Plugin Changeset View. Administrators should upgrade to the version that incorporates this changeset and verify that authorization checks are enforced in the affected Shortcodes.php handlers.
Workarounds
- Remove the plugin's subscription shortcodes from public-facing pages until a patched release is installed.
- Restrict access to pages embedding the affected shortcodes using WordPress role-based access controls or server-level authentication.
- Deploy a web application firewall rule that blocks unauthenticated requests to the affected shortcode endpoints.
# Configuration example: temporarily disable the plugin via WP-CLI
wp plugin deactivate 2download-connector
wp plugin delete 2download-connector
