CVE-2022-2444: Visualizer: Tables and Charts Manager for WordPress <= 3.7.9 - Authenticated (Contributor+) PHAR Deserialization

The Visualizer: Tables and Charts Manager for WordPress plugin for WordPress is vulnerable to deserialization of untrusted input via the 'remote_data' parameter in versions up to, and including 3.7.9. This makes it possible for authenticated attackers with contributor privileges and above to call files using a PHAR wrapper that will deserialize the data and call arbitrary PHP Objects that can be used to perform a variety of malicious actions granted a POP chain is also present. It also requires that the attacker is successful in uploading a file with the serialized payload.

Security readout for executives and security teams

Plain-English summary

CVE-2022-2444 affects the WordPress Visualizer plugin through version 3.7.9. A logged-in user with Contributor or higher privileges may be able to abuse chart remote data handling to trigger unsafe PHP object deserialization. Successful abuse has prerequisites, including uploading a crafted file and a usable object chain.

Executive priority

Treat as high priority for WordPress estates using this plugin, especially multi-author or customer-facing sites. The issue is not reported as actively exploited in the provided sources, but impact can be severe if prerequisites are met.

Technical view

The issue is CWE-502 deserialization of untrusted input through the remote_data parameter. Sources describe PHAR wrapper use causing serialized metadata to be deserialized, potentially leading to confidentiality, integrity, and availability impact if a POP chain exists. The advisory rates it CVSS 8.8 High.

Likely exposure

Exposure is limited to WordPress sites running Visualizer: Tables and Charts Manager at version 3.7.9 or earlier, with authenticated users at Contributor level or above who can reach the vulnerable workflow.

Exploitation context

The source bundle does not show CISA KEV listing or active exploitation. Exploitation is not described as unauthenticated; it requires at least Contributor privileges, successful malicious file upload, and a compatible PHP object chain.

Researcher notes

Focus review on remote_data handling and PHAR-related deserialization paths in Visualizer source and the 3.7.9 to 3.7.10 changes. Evidence supports authenticated Contributor-plus scope and prerequisite file upload; do not assume broader exploitation without new sources.

Mitigation direction

  • Upgrade Visualizer beyond affected versions, using vendor guidance for the fixed release.
  • Prioritize sites allowing Contributor or higher access to untrusted users.
  • Review and reduce unnecessary Contributor, Author, and Editor accounts.
  • If immediate upgrade is blocked, evaluate temporarily disabling the plugin.
  • Monitor vendor and Wordfence advisories for additional remediation details.

Validation and detection

  • Inventory WordPress sites using the Visualizer plugin.
  • Confirm installed Visualizer versions are newer than 3.7.9.
  • Review users with Contributor or higher roles on affected sites.
  • Check upload history and chart remote-data activity for anomalies.
  • Verify remediation through plugin version evidence after update.

Deserialization of Untrusted Data

Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
