Be the first to know when new zero-days emerge:

Summary

CVE-2026-78657 is a critical path traversal vulnerability (CWE-22) in the SigmaForms Pro – AI Generated Forms WordPress plugin by bdthemes, affecting all versions up to and including 1.4.11. The flaw allows unauthenticated attackers to cause arbitrary file deletion on the server, which can lead to remote code execution when a critical file such as wp-config.php is removed. The vulnerability carries a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Root cause: insufficient file path validation in the plugin’s delete_submission_files function.
  • Trigger conditions: an attacker submits a malicious path-traversal string via a form’s file upload field; this value is stored unvalidated in the WordPress database as part of the submission record.
  • Attack vector: network, no authentication or user interaction from the attacker required at submission time; the destructive action fires later when a site administrator deletes the stored submission from the WordPress admin panel, triggering deletion of the attacker-supplied path instead of (or in addition to) the intended upload.
  • Impact: arbitrary file deletion on the web server; deleting configuration files such as wp-config.php can force the site into a reinstallation state that can be leveraged for remote code execution, resulting in full compromise of confidentiality, integrity, and availability.

Affected software

  • bdthemes SigmaForms Pro – AI Generated Forms (WordPress plugin): all versions up to and including 1.4.11

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
