WordPress Core <= 7.0.3 - Authenticated (Author+) Remote Code Execution via Malicious File Upload

  • Disclosed: 12.08.2026
  • Updated: 11.10.2026 10:22

WordPress Core is vulnerable to Remote Code Execution in multiple release branches, including versions 4.7.0 through 7.0.3. This is due to insufficient validation in the WP_Image_Editor_Imagick::load() image-processing path before passing uploaded files or streams to Imagick, which can interpret attacker-supplied image-like files as PostScript-family or compressed delegate formats based on magic bytes, format specifiers, or decompressed content rather than the WordPress-accepted extension. This makes it possible for authenticated attackers, with Author-level access and above, to upload a crafted file that is processed during attachment metadata generation and may trigger unsafe ImageMagick/Ghostscript behavior, resulting in remote code execution on sites using Imagick and Ghostscript. Unauthenticated exploitation is deployment-dependent and requires an additional public-upload plugin or theme path that sends attacker-supplied files through WordPress image metadata generation.
