CVE-2022-0889: Ninja Forms - File Uploads Extension <= 3.3.12 - Reflected Cross-Site Scripting

The Ninja Forms - File Uploads Extension WordPress plugin is vulnerable to reflected cross-site scripting due to missing sanitization of the files filename parameter found in the ~/includes/ajax/controllers/uploads.php file which can be used by unauthenticated attackers to add malicious web scripts to vulnerable WordPress sites, in versions up to and including 3.3.12.

Security readout for executives and security teams

Plain-English summary

CVE-2022-0889 affects the Ninja Forms File Uploads WordPress extension through version 3.3.12. A public website using the vulnerable extension could reflect attacker-supplied script content through an unsanitized filename value, creating browser-side risk for visitors or administrators.

Executive priority

Treat this as a high-priority WordPress plugin update for public-facing sites. It is not confirmed as actively exploited in the provided sources, but unauthenticated browser-side impact makes delayed remediation risky.

Technical view

The issue is CWE-79 reflected cross-site scripting in the File Uploads extension upload controller, tied to missing sanitization of the files filename parameter. The CVSS 3.1 score is 7.2, with network access, low complexity, no privileges, and changed scope reported.

Likely exposure

Exposure is most likely on WordPress sites running Ninja Forms File Uploads 3.3.12 or earlier, especially where file upload form functionality is reachable from the public internet.

Exploitation context

The source bundle does not show CISA KEV listing or other cited evidence of active exploitation. Risk remains meaningful because the report describes unauthenticated attack access and low attack complexity on public WordPress surfaces.

Researcher notes

The affected-version evidence comes from the CVE description and Wordfence title. The bundle’s affected metadata is sparse and oddly lists version 0/default unaffected, so rely on the narrative references for practical scoping.

Mitigation direction

  • Update Ninja Forms File Uploads to 3.3.13 or later where available.
  • Check vendor guidance for any additional remediation or compatibility notes.
  • Temporarily disable public file upload forms if immediate updating is not possible.
  • Prioritize externally reachable WordPress sites and administrator-facing workflows.

Validation and detection

  • Inventory WordPress sites for the Ninja Forms File Uploads extension.
  • Confirm installed plugin versions are later than 3.3.12.
  • Verify public forms using file upload functionality are still required.
  • Review web security telemetry for suspicious filename-related XSS indicators.
