CVE-2024-47823Public exploitNetwork attack vector

Remote code execution via MIME-based extension spoofing

Published Oct 8, 2024 · Updated Jul 17, 2025

Unrestricted file upload in Livewire before 2.12.7 or 3.5.2 allows remote authenticated users to execute PHP code via a crafted upload. TemporaryUploadedFile::generateHashNameWithOriginalNameEmbedded derives the temporary suffix from attacker-controlled MIME data, so extension validation accepts a PHP filename disguised as image/png. Code execution requires application code to reuse the original filename, save on a public disk, and expose .php files to a PHP-enabled web server.
