CVE-2026-11363Network attack vector

Conditional code execution via unsafe form deserialization

Published Sep 9, 2026 · Updated Sep 9, 2026

PHP object injection in Saturday Drive Ninja Forms 3.14.6 and earlier allows remote authenticated users to inject objects via form import. WPN_Helper::build_nf_cache() calls get_settings() on imported action data, causing untrusted serialized settings to be deserialized automatically. Administrator access is required, and file deletion, data retrieval, or code execution requires a usable POP chain from another installed plugin or theme.
