Critical ImageMagick Vulnerability Exposes Millions to Remote Code Execution A critical vulnerability in ImageMagick, identified by Octagon Networks, allows remote code execution (RCE) through specially crafted image files. This 'magic byte shift' vulnerability affects major Linux distributions, including Ubuntu, Debian, and Amazon Linux, as well as WordPress sites using certain plugins like Gravity Forms. Attackers can exploit this flaw to bypass security policies and execute arbitrary code, potentially leading to data breaches and server control. Despite a fix being implemented in November 2025, it was not officially labeled as a security update, leaving many systems unpatched. Website administrators are currently responsible for manually securing their systems against this threat, which remains prevalent due to the lack of automated patches. The vulnerability poses a significant risk to millions of websites globally. 3 sources 67
