CVE-2025-53345Network attack vector

Authenticated code execution via unauthorized plugin installation

Published Jun 2, 2026 · Updated Jun 2, 2026

Missing authorization in ThimPress Thim Core 2.3.3 and earlier allows remote authenticated users to execute code via plugin installation. Public sources do not identify the affected endpoint or function, or the authorization check omitted before the installation action. Low-privileged WordPress access is required; installing a crafted malicious plugin then grants arbitrary code execution on the server.
