CVE-2026-1306
CriticalSummary
Wtyczka midi-Synth dla WordPressa jest podatna na nieautoryzowane przesyłanie plików z powodu braku walidacji typu pliku i rozszerzenia pliku w akcji AJAX 'export' we wszystkich wersjach do i włącznie z 1.1.0. Umożliwia to nieautoryzowanym atakującym przesyłanie dowolnych plików na serwer dotkniętej witryny.
Risk Assessment
Atakujący mogą przesyłać złośliwe pliki, co może prowadzić do zdalnego wykonania kodu, jeśli uzyskają ważny nonce. Ekspozycja nonce w JavaScript frontendowym sprawia, że jest on łatwo dostępny dla nieautoryzowanych atakujących.
Recommendation
Zaleca się aktualizację wtyczki midi-Synth do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto wdrożyć dodatkowe mechanizmy zabezpieczeń, takie jak walidacja plików na serwerze.

Original NVD description (English source)
The midi-Synth plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type and file extension validation in the 'export' AJAX action in all versions up to, and including, 1.1.0. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible granted the attacker can obtain a valid nonce. The nonce is exposed in frontend JavaScript making it trivially accessible to unauthenticated attackers.
