Summary

CVE-2025-6463 is a high-severity External Control of File Name or Path (CWE-73) vulnerability in Incsub Forminator. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked in the top 4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The Forminator Forms plugin for WordPress, used for building contact, payment, and custom forms, contains an arbitrary file deletion vulnerability in all versions through 1.44.2. The flaw stems from insufficient validation of file paths supplied to the entry_delete_upload_files function, which permits external control over the paths that are later processed during submission deletion.

Unauthenticated attackers can supply arbitrary file paths during form submission. When an administrator or the plugin's auto-deletion settings later removes the submission, the referenced file is deleted from the server. Successful exploitation of sensitive files such as wp-config.php can result in remote code execution, and the issue carries a CVSS 3.1 score of 8.8.

The EPSS score has remained flat at 0.0115 with no material increase since disclosure. Public references include the vulnerable code path in the plugin's form-entry-model.php and the corresponding changeset that addresses the path-handling logic.

Vulnerability Data

The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'entry_delete_upload_files' function in all versions up to, and including, 1.44.2. This…

more

makes it possible for unauthenticated attackers to include arbitrary file paths in a form submission. The file will be deleted when the form submission is deleted, whether by an Administrator or via auto-deletion determined by plugin settings. This can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly rejects or sanitizes untrusted path strings before they reach filesystem operations.

AC-3 Access Enforcement partial match

Enforces authorization checks on the actual resource accessed, blocking unauthorized files even when a malicious path is supplied.

AC-6 Least Privilege partial match

Least-privilege limits the set of files or directories any subject can affect, shrinking the blast radius of a path-control flaw.

PR.PS-06 full match
prevents

Secure SDLC practices include input validation and path sanitization that eliminate this weakness.

PR.AA-05 mostly match
prevents

Least-privilege file authorization directly limits damage from externally controlled paths.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect path-traversal issues but does not itself implement preventive controls.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent external file/path manipulation.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against untrusted input influencing file operations.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles discourage unsafe path construction but do not prescribe concrete file-name controls.

A.8.28 Secure coding partial match
prevents

Secure coding standards require canonicalization, allow-listing, and bounds checks on file paths, directly eliminating CWE-73.

A.8.3 Information access restriction partial match
mitigates

Information access restriction limits which files can be reached, indirectly reducing impact of path manipulation.
