description

Redirection for Contact Form 7 versions before 3.2.16 can accept personal-data export or erasure requests for email addresses without confirming that the requester controls them. An unauthenticated visitor may create requests that are treated as confirmed when the plugin's data-request form action is available under its default behavior.

mitigation

Update Redirection for Contact Form 7 to version 3.2.16 or later. Until the update is installed, disable or restrict access to the plugin's personal-data request form action.

fixed in 3.2.16

automationDeterministic: a check that runs on its own, the same request on every target. Contextual: an agentic technique that needs to be applied per target, for bugs that depend on contextual flows.
deterministic
auth requiredWhether an attacker needs an account first, based on the CVSS vector's Privileges Required.
