CVE-2025-47637Network attack vector

Unauthenticated web-shell upload via unchecked file type

Published May 23, 2025 · Updated Apr 28, 2026

Arbitrary file upload in STAGGS – Product Configurator Toolkit 2.11.0 and earlier allows remote attackers to place executable web shells. The public-facing WordPress Ajax upload path accepts a client-supplied file after relying on a nonce exposed in JavaScript, without authenticating the caller or validating the file type. No account or user interaction is required; successful upload permits attacker-controlled PHP execution in the site’s web-server context.
