The Custom Contact Forms plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.16. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to permanently force-delete arbitrary posts of any post type (including pages, administrator-authored posts, and WooCommerce products) and write arbitrary ccf_field_* post meta onto any post regardless of ownership or post type. The top-level form ID is checked via edit_post/publish_posts, but the nested fields[].ID and choices[].ID paths processed by _create_and_map_fields() and _create_and_map_choices() carry no equivalent capability or post-type guard, leaving those sinks fully exposed while delete_item() and delete_submission() contain explicit post-type restriction fixes demonstrating the developer's awareness of scoping requirements.
AnalysisAI
Authorization bypass in the Custom Contact Forms WordPress plugin (all versions ≤ 7.16) grants authenticated contributors the ability to permanently force-delete arbitrary posts of any type - including administrator-authored pages and WooCommerce product listings - and write arbitrary ccf_field_* post meta onto any post regardless of ownership. The root cause is that _create_and_map_fields() and _create_and_map_choices() accept arbitrary post IDs in nested fields[].ID and choices[].ID parameters with no capability or post-type validation, leaving those REST API sinks fully unguarded while the developer had already implemented equivalent guards elsewhere in the same controller. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated WordPress session with at minimum contributor role - the plugin's REST API endpoints validate the caller's identity but do not verify that the caller holds edit or delete capabilities over the post IDs supplied in the nested fields[].ID and choices[].ID parameters. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 4.3 vector (I:L/A:N) materially understates the real-world impact of this vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Update the Custom Contact Forms plugin to the release incorporating WordPress plugin Trac changeset r3669565 (https://plugins.trac.wordpress.org/changeset?reponame=&old=3669565%40custom-contact-forms&new=3669565%40custom-contact-forms); the exact patched version number should be confirmed in the WordPress plugin directory before deploying, as it is not independently specified in available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
