AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H
Network-reachable form submission with no auth (AV:N/PR:N), but deletion only fires when an admin views the entry (UI:R); arbitrary file deletion yields I:H/A:H with no direct read (C:N).

Lifecycle Timeline
2DescriptionCVE.org
The Database for Contact Form 7, WPforms, Elementor forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the view_page function in all versions up to, and including, 1.5.1. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Successful exploitation requires an administrator to view or edit the poisoned form entry, at which point PHP's bracket parser reshapes the attacker-crafted JSON key to bypass the stored-path isset check and trigger deletion of the traversal-specified file.
AnalysisAI
Arbitrary file deletion in the Database for Contact Form 7, WPforms, Elementor forms WordPress plugin (versions ≤1.5.1) allows remote unauthenticated attackers to poison form entries with traversal payloads that, when later viewed by an administrator, delete arbitrary server files and can be escalated to remote code execution by removing wp-config.php. Reported by Wordfence with publicly available exploit code exists via the Wordfence advisory; no public exploit identified at time of analysis as weaponized in-the-wild attacks, and the issue is not in CISA KEV.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The vulnerable plugin Database for Contact Form 7, WPforms, Elementor forms (contact-form-entries) version ≤1.5.1 must be installed and active on a WordPress site with at least one form whose submissions are routed through the plugin's entry storage. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H) accurately reflects a two-stage attack: anyone on the internet can plant the payload (PR:N), but the destructive action only fires when an administrator opens the poisoned entry (UI:R), which is highly likely on any active WordPress site that triages submissions. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker submits a contact form on a vulnerable WordPress site, embedding a crafted field name with bracket/JSON-key traversal payload pointing at wp-config.php; the entry is stored without immediate effect. When a site administrator later opens the entry in the Contact Form Entries admin UI, the view_page handler resolves the poisoned key, bypasses the isset() guard, and unlinks wp-config.php, causing WordPress to enter the installation wizard so the attacker can re-point the site to a database they control and gain full RCE - a primitive consistent with the technical detail published in the Wordfence advisory. |
| Remediation | Upstream fix available (changeset 3578556); released patched version not independently confirmed beyond '> 1.5.1', so administrators should update the Contact Form Entries plugin to the latest available release from the WordPress.org plugin repository as soon as it is published and verify the installed version is greater than 1.5.1. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Immediately disable or uninstall affected plugin versions (≤1.5.1); audit server logs for suspicious form submissions and file deletion attempts; if operations permit, temporarily disable form submission functionality. …
