Lifecycle Timeline
5DescriptionCVE.org
The Custom Fields WordPress plugin before 1.5.1 does not validate a user-supplied file path before deletion, allowing unauthenticated users to delete arbitrary files on the server (such as wp-config.php), which can lead to a full site takeover.
AnalysisAI
Arbitrary file deletion in the Custom Fields WordPress plugin before 1.5.1 allows unauthenticated attackers to delete any file on the server - including wp-config.php - leading to full site takeover. Because the plugin fails to validate a user-supplied path before deletion, a remote attacker needs no authentication or user interaction (CVSS 10.0). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions - remote unauthenticated exploitation against default configurations of the Custom Fields WordPress plugin (versions below 1.5.1). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are mixed but lean toward high priority for any site running this plugin. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends a single crafted, unauthenticated HTTP request to the vulnerable plugin endpoint with a traversal path such as '../../wp-config.php' as the file to delete. With wp-config.php gone, the attacker loads the site, is presented with the WordPress installation wizard, and reconfigures it against a database they control - obtaining full administrative access. … |
| Remediation | Vendor-released patch: upgrade the Custom Fields plugin to version 1.5.1 or later, which adds validation of the user-supplied file path before deletion. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Begin immediately: audit all WordPress instances for the Custom Fields plugin and disable it on affected systems as an emergency measure while initiating your patch deployment process. …
