CVE-2024-0963: Calculated Fields Form <= 1.2.52 - Authenticated (Contributor+) Stored Cross-Site Scripting

The Calculated Fields Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's CP_CALCULATED_FIELDS shortcode in all versions up to, and including, 1.2.52 due to insufficient input sanitization and output escaping on user supplied 'location' attribute. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Security readout for executives and security teams

Plain-English summary

A WordPress plugin used for calculated forms can let logged-in contributors place harmful script into a page through a shortcode setting. The script runs when someone views that page, creating risk to site integrity and browser-accessible user data.

Executive priority

Prioritize normal patch management, with faster handling for sites with many content contributors or untrusted contributor accounts. This is not marked as actively exploited in the provided sources.

Technical view

CVE-2024-0963 is stored cross-site scripting in Calculated Fields Form through the CP_CALCULATED_FIELDS shortcode location attribute. Sources attribute it to insufficient input sanitization and output escaping in versions up to and including 1.2.52. CVSS is 6.4, CWE-79.

Likely exposure

Exposure is likely on WordPress sites running Calculated Fields Form version 1.2.52 or earlier, especially where contributor-level or higher accounts can create or edit content containing plugin shortcodes.

Exploitation context

The source bundle says exploitation requires an authenticated contributor-level or higher user. It does not identify public exploitation, and KEV status is false. The payload would execute when a user accesses an affected injected page.

Researcher notes

The vulnerability is a shortcode-attribute stored XSS issue. The supplied WordPress Trac changeset references the affected plugin file, but the bundle does not provide exploit telemetry or detailed vendor hardening guidance beyond the affected version boundary.

Mitigation direction

  • Update Calculated Fields Form to a version newer than 1.2.52 or the latest vendor-recommended release.
  • Restrict contributor-level and higher accounts to trusted users only.
  • Review pages and posts using the CP_CALCULATED_FIELDS shortcode.
  • Check vendor and Wordfence guidance for any additional remediation instructions.
  • Remove unexpected script-bearing content from affected WordPress pages or posts.

Validation and detection

  • Inventory WordPress sites using the Calculated Fields Form plugin.
  • Confirm installed plugin versions are newer than 1.2.52.
  • Review contributor and author accounts for unnecessary publishing or editing access.
  • Search content for CP_CALCULATED_FIELDS shortcodes using the location attribute.
  • Inspect suspect pages for unexpected stored scripts or unauthorized edits.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
