CVE-2026-53466 with a CVSS score of 6.5 is a heap buffer over-read vulnerability affecting the Magick.NET framework. This technical flaw originates from an integer conversion overflow within the XCF decoder, which causes improper handling of data during image processing operations. An attacker can exploit this issue remotely over a network without any required privileges or user interaction by persuading a system to process a maliciously crafted image file. Successful exploitation triggers an out-of-bounds read, granting the attacker the potential to access limited sensitive information from memory or induce a denial-of-service condition through an application crash. The primary business impact involves the disruption of service availability, which could interrupt critical workflows and negatively affect system reliability. Exploitation is contingent upon the target system utilizing the vulnerable library to decode a specifically malformed XCF image file provided by the attacker.
