CVE-2026-4843 mrdollar4444 CVE debrief

Who should care

WordPress site owners and administrators running GSheet For Woo Importer, especially sites that allow Subscriber-level accounts or other low-privilege authenticated users. Teams relying on the plugin’s Google Sheets API token and configuration should treat this as a configuration-loss risk.

Technical summary

Wordfence attributes the issue to process_ajax_restore_action() in the plugin source and cites a missing capability check. Because the action is reachable by authenticated users, an attacker with PR:L access can delete the plugin’s Google Sheets API token and configuration options. The NVD vector is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N, aligning with a broken-access-control weakness (CWE-862) and limited integrity impact.

Defensive priority

Medium. Patch promptly on any site that uses the plugin, and raise priority if the plugin protects production automation or sensitive Google Sheets credentials. The CVSS score is 4.3, but the practical impact can include loss of configuration and interruption of imports.

Recommended defensive actions

• Update GSheet For Woo Importer to a fixed version as soon as one is available; the issue affects all versions up to and including 2.3.1.
• Review the plugin’s Google Sheets API token and configuration after any unexpected resets or administrative changes.
• Limit low-privilege authenticated access where possible, and monitor for suspicious restore or settings-change activity.
• Check backups and site logs for unauthorized deletion of the plugin’s token or configuration options.
• If you cannot remediate quickly, consider disabling the plugin until a corrected release is deployed.
