CVE-2023-3814Public exploitNetwork attack vector

Arbitrary file reads via multisite authorization bypass

Published Sep 4, 2023 · Updated Mar 6, 2025

Incorrect authorization in Advanced File Manager before 5.1.1 allows remote authenticated users to read server files on WordPress multisite. The plugin exposes its server-side file manager to site administrators because the multisite access gate does not require network super-administrator status; no function-level locus is publicly documented. A multisite deployment and site-administrator account are required, and successful access exposes directory listings and readable files within the configured filesystem reach.
