CVE-2026-106579: ImageMagick coder security policy bypass

CVE-2026-106579 · Severity: medium · CVSS 6.2 · Published 2026-10-07

ImageMagick is a widely-used image editing library that enforces security policies to control which image formats can be read and written. A crafted image file can circumvent these policies, allowing an attacker to read or process image data that should have been blocked, potentially exposing sensitive information in systems that rely on policies to restrict dangerous image codecs.

Technologies: ImageMagick. Vendors: ImageMagick.

Technical details

The vulnerability is a policy validation bypass in the coder authorization check during image read and write operations. The flaw exists in MagickCore/constitute.c where the wrong variable is passed to the IsCoderAuthorized function, causing the policy check to evaluate against an incorrect coder identifier. An attacker can supply a crafted image that bypasses coder-based security policies without requiring authentication or special privileges.
