Why it matters

CVE-2026-106098 is a vulnerability in the WP Data Access WordPress plugin that allows unauthenticated attackers to modify data in an application exposed for anonymous read access. Defenders should prioritize verifying the version in use, reviewing the plugin's configuration, and monitoring for unauthorized modifications.

• Defenders need to verify the version of WP Data Access in use and update to 5.5.77 or later to prevent unauthorized modifications.
• They should review the plugin's configuration to ensure that update actions are properly disabled.
• Defenders should monitor for any unauthorized modifications to the application data.

Technical summary

The WP Data Access WordPress plugin before version 5.5.77 does not correctly check authorization on one of its application REST endpoints, verifying only read permission before performing a write. This allows unauthenticated attackers to modify data in an application exposed for anonymous read access, even when update actions have been disabled by the administrator. Affected product deployments should be identified in managed environments, and defenders should review the plugin's configuration to ensure that update actions are properly disabled and monitor for any unauthorized modifications. The vulnerability requires verification of the affected scope and remediation priority.
