CVE-2026-11395

CF7 to Webhook <= 5.0.0 - Unauthenticated Server-Side Request Forgery via CF7 Field Placeholder in Webhook URL Host

Published Jun 18, 2026 CVSS 3.1 · 7.2 High EPSS < 1% KEV · Not listed

Description

The CF7 to Webhook plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 5.0.0 via the pull_the_trigger. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. Exploitation requires that the admin-configured webhook URL contains a Contact Form 7 field placeholder in the host segment of the URL, and that the affected form is publicly accessible.

Analysis

Technical impact

The CF7 to Webhook plugin for WordPress contains an SSRF flaw triggered by the pull_the_trigger method. By embedding a Contact Form 7 field placeholder in the host portion of an admin‑configured webhook URL, an unauthenticated attacker can cause the application to send HTTP requests to arbitrary destinations. This allows the attacker to read sensitive data or manipulate internal services, potentially leading to data disclosure, integrity violations, or further compromise.

Affected Systems

The vulnerability affects the Maria Valney CF7 to Webhook WordPress plugin in all releases up to and including version 5.0.0. Any WordPress site that has this plugin installed and exposes a Contact Form 7 form publicly may be impacted.

Risk and Exploitability

The CVSS base score of 7.2 indicates high severity, while the EPSS score of < 1% implies a very low probability of exploitation at this time. The flaw is not listed in CISA’s KEV catalog. Exploitation requires a publicly accessible form and the presence of a placeholder in the webhook URL host; unauthenticated attackers can trigger it directly via the pull_the_trigger endpoint.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Upgrade the CF7 to Webhook plugin to a version newer than 5.0.0, which removes the SSRF vulnerability.
If an upgrade is not immediately feasible, eliminate placeholder usage in the host segment of any webhook URLs or disable the pull_the_trigger functionality altogether.
Restrict access to the affected Contact Form 7 forms so that only authenticated users can trigger the plugin, reducing the attack surface.
