This vulnerability exposes a critical gap in server-side security where widely used image processing libraries like libheif can be exploited via malicious HEIC uploads to achieve remote code execution on WordPress sites. The attack leverages a memory corruption flaw that redirects program execution during the decoding of uncompressed images, highlighting risks inherent in handling modern mobile photo formats without rigorous input validation. While currently limited to authenticated users with upload permissions and not an active global outbreak, this finding underscores the necessity for developers to audit third-party media libraries against similar parsing vulnerabilities.

A malicious HEIC image can become a route to remote code execution on a WordPress server. Researchers have demonstrated an attack chain that turns a normal Media Library upload into code execution in the PHP-FPM process that runs the site.

A malicious HEIC image can become a route to remote code execution on a WordPress server. Researchers have demonstrated an attack chain that turns a normal Media Library upload into code execution in the PHP-FPM process that runs the site. The risk comes from libheif, a widely used component that reads HEIC, HEIF and AVIF files. When WordPress sends an uploaded image to ImageMagick for resizing, a specially crafted file can reach the vulnerable…
