AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Payload is injected unauthenticated over the network (PR:N), but deletion executes only when an administrator deletes the submission, so UI:R; deleting wp-config.php enables full compromise, giving C:H/I:H/A:H.

The SigmaForms Pro - AI Generated Forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete_submission_files function in all versions up to, and including, 1.4.11. 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). The malicious path traversal URL is submitted via form upload field and stored in the database, with deletion triggered when an administrator deletes the submission record from the admin panel.

AnalysisAI
Arbitrary file deletion in the SigmaForms Pro - AI Generated Forms plugin for WordPress (all versions through 1.4.11) lets unauthenticated attackers submit a path-traversal string through a form's file-upload field, which is stored in the database and processed by the vulnerable delete_submission_files function. When an administrator later deletes the submission record, the plugin removes the attacker-specified file - deleting wp-config.php (or similar) can escalate to full site takeover/remote code execution. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the SigmaForms Pro plugin (≤1.4.11) to be installed and active with a public form that exposes a file-upload field, through which the attacker stores a path-traversal value unauthenticated. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The Wordfence-assigned CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N, C:H/I:H/A:H = 9.8) treats this as trivially remote and unauthenticated, but the description reveals an important nuance: while the malicious payload is injected without authentication, the destructive deletion only fires when a logged-in administrator deletes the submission record from the admin panel. … 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 SigmaForms Pro to the first release above 1.4.11 as published by BdThemes once available; the input data does not include a confirmed fixed version, so verify the exact patched build against the vendor announcements page (https://feedback.bdthemes.com/announcements) and the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/c714e2b3-8a96-4078-99a4-4ce620939828?source=cve) - no vendor-released patch version is independently confirmed at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: immediately deactivate and remove the SigmaForms Pro plugin from all affected WordPress instances and audit the database for malicious form submissions containing path-traversal sequences. …
