Lifecycle Timeline
2DescriptionNVD
The FormGent plugin for WordPress is vulnerable to unauthorized arbitrary file deletion due to a missing capability check on the /wp-json/formgent/responses/attachments REST API endpoint in all versions up to, and including, 1.9.2 This is due to the REST API route being registered without any authentication middleware in routes/rest/api.php. This makes it possible for unauthenticated attackers to delete arbitrary files within the formgent uploads directory. Additionally, on Linux servers where the wp-content/uploads/formgent directory does not yet exist (the default state after plugin installation), the path traversal protection can be bypassed, enabling deletion of arbitrary files including wp-config.php which can lead to complete site takeover via a fresh WordPress installation.

Unauthorized arbitrary file deletion in the FormGent WordPress plugin (versions up to and including 1.9.2) allows unauthenticated remote attackers to delete files via the /wp-json/formgent/responses/attachments REST endpoint, which was registered with no authentication middleware. On Linux hosts where the wp-content/uploads/formgent directory has not yet been created (the default post-install state), path-traversal protections can be bypassed to delete files outside the intended directory, including wp-config.php - enabling full site takeover through the fresh-install re-configuration flow. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network access to the WordPress REST API path /wp-json/formgent/responses/attachments on a site running FormGent version 1.9.2 or earlier; no authentication, credentials, or user interaction are needed (PR:N/UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are consistent and point to a genuine high priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends an unauthenticated HTTP request to /wp-json/formgent/responses/attachments on a target WordPress site running FormGent ≤ 1.9.2, specifying a traversal path to delete wp-config.php on a Linux host where the formgent uploads directory has not been created. With the config file gone, WordPress serves its install wizard, letting the attacker re-initialize the site against a database they control and seize full administrative control. … |
| Remediation | Vendor-released patch: 1.10.0 - update the FormGent plugin to version 1.10.0 or later, which adds the missing authorization/permission check to the attachments REST route (see the fix changeset https://plugins.trac.wordpress.org/changeset/3604540/formgent/trunk/app/Http/Controllers/AttachmentController.php). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, deactivate the FormGent WordPress plugin (all versions ≤1.9.2) on all affected sites immediately, then completely remove the plugin from wp-content/plugins/ to eliminate the attack vector. …
