Security readout for executives and security teams
Plain-English summary
A WordPress site using CodePeople Calculated Fields Form up to version 1.1.120 may let a logged-in user submit feedback without proper authorization. Business impact appears limited to low integrity impact, but exposed public sites should still treat it as a plugin governance and abuse risk.
Executive priority
Prioritize during normal WordPress maintenance unless the plugin is deployed on high-traffic or account-enabled sites. It is not sourced as actively exploited, but plugin authorization flaws can create operational noise and trust issues if ignored.
Technical view
CVE-2023-26523 is a CWE-862 missing authorization issue in the WordPress Calculated Fields Form plugin through 1.1.120. The CVSS 3.1 score is 4.3, with network access, low complexity, low privileges required, no user interaction, and low integrity impact.
Likely exposure
Exposure is likely limited to WordPress installations that have CodePeople Calculated Fields Form installed at version 1.1.120 or earlier. The provided sources do not identify other affected products or deployment-specific prerequisites beyond the plugin and authenticated access.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The CVSS vector indicates exploitation requires a low-privileged authenticated user and does not require user interaction.
Researcher notes
The vulnerability is classified as missing authorization, CWE-862. CVSS shows integrity-only impact and authenticated access requirement. Public evidence in the provided bundle is sparse; do not assume exploit availability, unauthenticated impact, or a specific fixed version without vendor confirmation.
Mitigation direction
- Inventory WordPress sites for the Calculated Fields Form plugin and version.
- Check CodePeople or WordPress plugin guidance for a fixed version or official mitigation.
- Upgrade beyond version 1.1.120 if a vendor-supported fixed release is available.
- Disable the plugin where it is unnecessary or no vendor fix is available.
- Limit untrusted account creation and review low-privilege user permissions.
Validation and detection
- Confirm whether any site runs Calculated Fields Form version 1.1.120 or earlier.
- Review plugin changelogs or vendor advisory for authorization-related fixes.
- Check logs for unexpected feedback submissions by low-privilege users.
- Verify compensating controls restrict untrusted authenticated access.
- Document affected sites, plugin versions, and remediation status.
