CVE-2026-1056: Snow Monkey Forms <= 12.0.3 - Unauthenticated Arbitrary File Deletion via Path Traversal

The Snow Monkey Forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'generate_user_dirpath' function in all versions up to, and including, 12.0.3. 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).

Security readout for executives and security teams

Plain-English summary

CVE-2026-1056 affects the Snow Monkey Forms WordPress plugin through version 12.0.3. An unauthenticated attacker may delete files on the web server. Deleting critical WordPress files can break the site and may enable full compromise. Prioritize any public WordPress site using this plugin.

Executive priority

Treat as urgent for any internet-facing WordPress site using Snow Monkey Forms. The business risk is site outage, data exposure, or server takeover if critical files are removed. Patch or disable quickly after confirming exposure.

Technical view

The issue is path traversal from insufficient file path validation in generate_user_dirpath. Sources connect the vulnerable flow to REST/view handling and directory operations in version 12.0.3. CVSS is 9.8: network exploitable, low complexity, no privileges, no user interaction, with high confidentiality, integrity, and availability impact.

Likely exposure

Internet-facing WordPress sites with Snow Monkey Forms installed at version 12.0.3 or earlier are the primary exposure. The source bundle does not establish exposure for other products.

Exploitation context

CISA KEV is false in the provided bundle, and no cited source states active exploitation. However, the vulnerability is unauthenticated, low-complexity, and can delete arbitrary server files, making exploitation consequences severe if reachable.

Researcher notes

The public record names CWE-22 and points to generate_user_dirpath plus related WordPress Trac code and changeset references. The provided affected metadata is inconsistent, so rely on the narrative statement: all versions up to and including 12.0.3.

Mitigation direction

  • Identify all WordPress sites running Snow Monkey Forms.
  • Update Snow Monkey Forms beyond 12.0.3 when vendor guidance confirms a fixed release.
  • If no fix is available, disable the plugin until vendor guidance is clear.
  • Restrict public access to affected forms where business impact permits.
  • Ensure recent, restorable backups of WordPress files and configuration.

Validation and detection

  • Inventory plugin versions across WordPress environments.
  • Confirm whether Snow Monkey Forms is version 12.0.3 or earlier.
  • Review WordPress and web server logs for suspicious unauthenticated form or REST requests.
  • Check for unexpected missing or modified WordPress configuration files.
  • Monitor vendor, WordPress.org, and Wordfence pages for confirmed fix details.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
