CVE-2026-73386 Overview
CVE-2026-73386 is an unauthenticated sensitive data exposure vulnerability in the WordPress plugin Track Geolocation Of Users Using Contact Form 7. The flaw affects plugin versions up to and including 3.0.2. Remote attackers can retrieve sensitive information over the network without authentication or user interaction. The issue is classified under CWE-201: Insertion of Sensitive Information Into Sent Data.
The vulnerability exposes geolocation data collected from users who submit Contact Form 7 forms. This data can include IP addresses, geographic coordinates, and related metadata tracked by the plugin.
Critical Impact
Unauthenticated attackers can access geolocation records tied to form submissions, enabling reconnaissance and privacy violations against site visitors.
Affected Products
- WordPress plugin Track Geolocation Of Users Using Contact Form 7
- Plugin versions <= 3.0.2
- WordPress installations that expose the plugin's data endpoints to the public internet

Technical Details for CVE-2026-73386
Vulnerability Analysis
The plugin extends Contact Form 7 by recording geolocation details for each form submission. Versions up to 3.0.2 expose stored geolocation data without enforcing authentication or authorization checks. Remote attackers can query the plugin's data pathways directly and retrieve information intended for site administrators.
The attack requires no privileges and no user interaction. Confidentiality is directly impacted, while integrity and availability remain unaffected. The EPSS score of 0.245% reflects a low predicted probability of near-term exploitation, though the low complexity of unauthenticated data retrieval keeps the risk material for exposed WordPress sites.
Root Cause
The root cause is missing access control on data output paths that surface stored geolocation records. The plugin does not validate the requester's identity or role before returning sensitive submission metadata. This aligns with the CWE-201 pattern of inserting sensitive information into responses accessible to unintended parties.
Attack Vector
The attack vector is network-based over standard HTTP or HTTPS. An attacker sends crafted requests to the vulnerable WordPress endpoints exposed by the plugin. Because the endpoints do not require authentication, any remote actor with network reachability to the site can extract geolocation data. See the Patchstack Vulnerability Report for advisory details.
No verified public proof-of-concept code is available at this time. The vulnerability mechanism is described here in prose rather than with synthetic exploit code.
Detection Methods for CVE-2026-73386
Indicators of Compromise
- Repeated unauthenticated HTTP requests targeting plugin-specific endpoints under /wp-content/plugins/track-geolocation-of-users-using-contact-form-7/ or associated REST routes.
- Web server access logs showing bulk retrieval of geolocation records from a small set of source IP addresses.
- Outbound responses containing IP addresses, latitude, and longitude fields correlated with form submission identifiers.
Detection Strategies
- Inventory WordPress sites and identify installations of Track Geolocation Of Users Using Contact Form 7 version 3.0.2 or earlier.
- Alert on anonymous access patterns to plugin data endpoints, particularly high-volume sequential requests.
- Correlate WordPress access logs with WAF telemetry to detect enumeration behavior against Contact Form 7 tracking data.
Monitoring Recommendations
- Ingest WordPress and reverse proxy logs into a centralized analytics platform for anomaly detection on plugin routes.
- Track version metadata across managed WordPress hosts to flag vulnerable plugin releases automatically.
- Monitor for unusual geographic distribution of successful HTTP 200 responses from plugin endpoints.
How to Mitigate CVE-2026-73386
Immediate Actions Required
- Update the Track Geolocation Of Users Using Contact Form 7 plugin to a version newer than 3.0.2 once released by the vendor.
- If no fixed version is available, deactivate and remove the plugin from affected WordPress sites.
- Review web server access logs for prior unauthenticated access to plugin data endpoints and assess exposure of collected user data.
Patch Information
Refer to the Patchstack Vulnerability Report for the latest fix status and vendor guidance. Administrators should apply plugin updates through the WordPress dashboard as soon as a patched release is published.
Workarounds
- Block public access to plugin data endpoints at the web application firewall (WAF) until a patch is applied.
- Restrict access to /wp-content/plugins/track-geolocation-of-users-using-contact-form-7/ paths using web server access rules.
- Purge stored geolocation records that are no longer required to reduce the impact of any successful data extraction.
