Description
The Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder with AI plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.6.2 via the get_entry due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with custom-level access and above, to view, read, and permanently delete forms and entries belonging to any other user — including personally identifiable information submitted through public contact and lead forms — regardless of form ownership.

AI Analysis

Impact

The vulnerability is an insecure direct object reference found in the get_entry functionality of the Everest Forms plugin for WordPress, up to version 3.6.2. An attacker who has authenticated credentials at the custom-level or higher can supply arbitrary identifiers to the JSON‑RPC /tools/call endpoint and retrieve or delete any form or entry, including personally identifiable information, without regard to the original form owner. This permits confidentiality compromise of sensitive user data and integrity loss as well as the potential for denial of service by removing legitimate entries.

Affected Systems

The affected product is the WordPress plugin Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder with AI, versions up to and including 3.6.2. The vulnerability is not tied to a specific WordPress core version, but applies to any site running the plugin within the stated range.

Risk and Exploitability

The CVSS score of 6.5 indicates moderate severity. EPSS information is not available, and the vulnerability is not listed in CISA KEV. The attack requires the attacker to be authenticated and possess user roles of custom+ or higher. Once credentials are obtained or standard site permissions are exploited, the attacker can invoke the vulnerable endpoint to read or delete arbitrary objects, with no network boundary constraints other than the WordPress site itself.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade Everest Forms to version 3.6.3 or later to remove the insecure direct object reference.
  • Restrict permissions for the /tools/call JSON‑RPC endpoint by disabling the get_entry ability for all roles except administrators, or by removing the custom+ role entirely.
  • If an upgrade is not possible, disable or remove the get_entry capability in the plugin’s abilities registry via custom code or a child‑theme function hook.
