Security readout for executives and security teams

Plain-English summary

CVE-2023-45771 is a reflected cross-site scripting flaw in the WordPress Contact Form With Captcha plugin through version 1.6.8. A victim must interact with a crafted request or link. Successful exploitation could expose or alter limited browser-session data in the affected site context.

Executive priority

Treat as high priority for public WordPress sites using this plugin, especially where staff or customers authenticate. It is not proven actively exploited from the supplied sources, but XSS in public forms can create brand, data, and account-risk exposure.

Technical view

The issue is CWE-79 improper neutralization of input during web page generation. The CVSS 3.1 score is 7.1 with network access, low attack complexity, no privileges required, user interaction required, and changed scope. The provided sources identify the package as contact-form-with-captcha and affected versions through 1.6.8.

Likely exposure

Exposure is likely limited to WordPress sites that have Contact Form With Captcha installed at version 1.6.8 or earlier. The bundle provides no CPEs and no evidence of exposure outside that plugin.

Exploitation context

The CVE is not listed as KEV in the bundle, and no cited source states active exploitation. The vulnerability is reflected XSS, so exploitation depends on getting a user to visit or submit attacker-influenced content to the affected site.

Researcher notes

Evidence is sparse: the bundle identifies reflected XSS, CVSS 7.1, CWE-79, and affected versions through 1.6.8, but does not include payload details, patch version, exploit status, or detailed vulnerable parameters. Avoid assuming broader product impact.

Mitigation direction

  • Inventory WordPress sites for the contact-form-with-captcha plugin and version.
  • Check vendor or Patchstack guidance for a fixed version or recommended remediation.
  • Disable or remove the plugin where no validated fix is available.
  • Prioritize remediation on public sites with authenticated users or administrators.

Validation and detection

  • Confirm whether contact-form-with-captcha is installed and at or below version 1.6.8.
  • Verify remediated sites no longer run vulnerable plugin versions.
  • Review web and application logs for unusual requests to contact form endpoints.
  • Document affected sites, remediation status, and any compensating controls.
