CVE-2023-44258Network attack vector

Unauthenticated state modification via missing request checks

Published Jan 2, 2025 · Updated May 11, 2026

Missing authorization in Schema App Structured Data 1.23.1 and earlier allows remote attackers to alter plugin state through unprotected requests. The affected request handlers omit capability or nonce checks; the earlier page_init path deletes the plugin's cached transients when invoked. No account or user interaction is required, and the documented consequence is limited to unauthorized plugin-state changes and transient deletion.
