CVE-2025-12973Public exploitNetwork attack vector

Authenticated code execution via PHP upload allowlist

Published Nov 21, 2025 · Updated Nov 21, 2025

Unrestricted file upload in Soft2Business S2B AI Assistant 1.7.8 and earlier allows remote authenticated users to execute server code. The storeFile() path accepts PHP in its custom extension allowlist and writes supplied bytes under wp-content/uploads without safe type validation. Editor-level access is required, and execution depends on the web server treating the uploaded PHP file as executable.
