CVE-2025-14071Network attack vector

Authenticated object injection via shortcode deserialization

Published Dec 21, 2025 · Updated Dec 21, 2025

PHP object injection in Live Composer Page Builder 2.0.2 and earlier allows remote authenticated users to inject objects via a shortcode. The dslc_module_posts_output handler passes attacker-controlled shortcode content to PHP unserialize(), then rewrites malformed serialized string lengths and retries deserialization. Contributor access is required, and file deletion, data access, or code execution depends on another installed plugin or theme supplying a usable POP chain.
