CVE-2025-12138
HighSummary
Wtyczka URL Image Importer dla WordPressa jest podatna na nieautoryzowane przesyłanie plików z powodu niewystarczającej walidacji typu pliku we wszystkich wersjach do i włącznie z 1.0.6. Problem wynika z polegania wtyczki na nagłówku Content-Type HTTP kontrolowanym przez użytkownika do walidacji przesyłanych plików.
Risk Assessment
Atakujący z poziomem dostępu Autora lub wyższym może przesyłać dowolne pliki na serwer dotkniętej witryny, co może prowadzić do zdalnego wykonania kodu poprzez przesłany plik PHP.
Recommendation
Zaleca się aktualizację wtyczki do najnowszej wersji oraz wdrożenie dodatkowych mechanizmów walidacji przesyłanych plików, aby zminimalizować ryzyko nieautoryzowanego dostępu.

- CVE-2025-12999Critical
A vulnerability in Open VSX allows an unauthenticated attacker to poison the per-extension metadata cache by supplying a crafted X-Forwarded-Host header, replacing download, signature, and public-key URLs with attacker-controlled ones. The cache keys do not include the host, so poisoned entries are served to all clients for the entry's lifetime (1 hour by default, cluster-wide with Redis).
- CVE-2026-82187Critical
The Web to Print Online Designer WordPress plugin before 2.15.0 does not validate the type or extension of uploaded files, and hands the token protecting those uploads to any visitor who asks for it. This allows unauthenticated attackers to upload arbitrary files, including PHP ones, and run code on the server.

Original NVD description (English source)
The URL Image Importer plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in all versions up to, and including, 1.0.6. This is due to the plugin relying on a user-controlled Content-Type HTTP header to validate file uploads in the 'uimptr_import_image_from_url()' function which writes the file to the server before performing proper validation. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible via the uploaded PHP file.
