CVE-2026-59534: Post My CF7 Form <= 6.2.0 Missing Authorization PoC, Patch Analysis & Rule

Severity Medium (CVSS 5.3)
CWE 862
Vulnerable Version 6.2.0
Patched Version 7.0.0
Disclosed July 22, 2026

Analysis Overview

Atomic Edge analysis of CVE-2026-59534: The Post My CF7 Form plugin for WordPress, version 6.2.0 and earlier, contains a missing authorization vulnerability that allows unauthenticated attackers to modify form-to-post mappings and delete saved submission data. The vulnerability has a CVSS score of 5.3 (MEDIUM). Atomic Edge research has identified that the root cause lies in the handling of quick-edit operations in the admin interface.

Root Cause: The vulnerability stems from missing capability checks in the partial template files used for the WordPress quick-edit functionality. The vulnerable code is in ‘post-my-contact-form-7/admin/partials/c2p-quick-edit.php’ and ‘post-my-contact-form-7/admin/partials/cf7-2-custom-post-quick-edit.php’. Before the patch, these files directly output the quick-edit interface without verifying that the current user has the necessary ‘manage_options’ capability. While the functions ‘save_quick_edit’ and ‘save_quick_custompost’ in ‘class-cf7-2-post-admin.php’ do contain a capability check, the permission validation is missing at the template level where the nonce field is output and the interface is displayed.

Exploitation: An attacker can exploit this vulnerability by sending a crafted POST request directly to the WordPress admin ‘admin-post.php’ endpoint, which handles the quick-edit save operations. The request would not require any authentication, allowing the attacker to invoke the ‘save_quick_edit’ or ‘save_quick_custompost’ functions. By supplying the ‘delete_c2p_map’ parameter with the ID of a target form, the attacker can force the plugin to delete the mapping and all associated saved submissions for that form. The nonce check is insufficient as a security boundary since a missing nonce only causes the function to return early, but the attacker does not need a nonce if the goal is to trigger unauthorized actions via the missing capability check.

Patch Analysis: The patch addresses the missing authorization by adding a capability check directly within the partial template files. In ‘c2p-quick-edit.php’ and ‘cf7-2-custom-post-quick-edit.php’, a check is now performed at the top using current_user_can( $capability ) with the ‘cf7_2_post_mapping_capability’ filter, which defaults to ‘manage_options’. If unauthorized, the function returns early and the quick-edit interface is not rendered or processed. This ensures that only authenticated users with the required capability can access these functions. Additionally, the patch removes the redundant capability checks from ‘modify_cf72post_custom_column’ and ‘modify_cf7_list_columns’ in ‘class-cf7-2-post-admin.php’, centralizing the authorization in the partials.

Impact: Successful exploitation of this vulnerability allows an unauthenticated attacker to perform a destructive action. Specifically, they can delete the form-to-post mapping configuration for any Contact Form 7 form and permanently erase all related saved submissions. This can result in significant data loss and disruption of the site’s form submission functionality. The financial and operational impact can be substantial, especially for sites that rely on form data for business processes.
