Redirection for Contact Form 7: Missing ownership check in data request form
Summary
The Redirection for Contact Form 7 WordPress plugin does not verify that the email address submitted through its data request form belongs to the requester. By default, the resulting request is recorded as already confirmed. An unauthenticated visitor can therefore create verified erasure or export requests for addresses they do not control, which can disrupt data handling or cause confusion and complaints. No login is required, but the public form must be reachable.
Affected
- Redirection for Contact Form 7 (wpcf7-redirect) 2.6.0 to before 3.2.16
Fixed in
- Fixed in 3.2.16
Workaround
- No workaround documented by the CNA.
- Third-party suggestion (VulDB): disable the data request form until the update is applied, if it is not needed for compliance.
Exploitation
- Not listed in CISA KEV.
- No public exploit code or nuclei template known as of 10 Nov 2026.
- No in-the-wild exploitation reported. A missing record does not prove safety.
Our recommendation
- Update the plugin to 3.2.16 or later.
- If the data request form is not needed for compliance, disable it until the update is applied.
- Review pending and recent erasure and export requests for entries you did not expect.
- Hold requests with unverified email addresses before acting on them.
- Keep the plugin current, as it has had several other unauthenticated flaws.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
The Redirection for Contact Form 7 WordPress plugin before 3.2.16 does not verify ownership of the email address supplied through its data request form action and by default records the resulting request as already confirmed, allowing unauthenticated visitors to create verified WordPress personal data erasure or export requests for addresses they do not control.
