CVE-2022-40357Public exploitNetwork attack vector

SSRF via unrestricted UEditor source URLs

Published Sep 20, 2022 · Updated May 28, 2025

SSRF in Z-BlogPHP 1.7.2 and earlier allows remote attackers to make arbitrary server-side requests through the UEditor crawler. The catchimage route passes each unrestricted source URL to saveRemote, which checks only for an http prefix before calling get_headers. This permits intranet service probing; the public proof uses an administrator session cookie, although the record classifies access as unauthenticated.
