CVE-2026-40500
ProcessWire: server-side request forgery vulnerability in the admin panel's 'Add Module From URL' feature
Impact
Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. The "Add Module from URL" feature requires superuser privileges (root-equivalent in ProcessWire) who already has unrestricted arbitrary code execution via standard module upload, making the SSRF vector incapable of providing incremental attack surface. The feature is also disabled by default and requires direct filesystem access to enable.
