Doc Text:
A flaw was found in ImageMagick. An attacker can bypass security policy restrictions by providing a crafted image when policies are configured using the coder domain rather than the module domain. Successful exploitation causes the application to process image formats that administrators intended to block, potentially resulting in unauthorized information disclosure.

Description OSIDB Bzimport 2026-10-08 14:24:13 UTC
ImageMagick before 6.9.13-56 and 7.x before 7.1.2-31 allows a security policy bypass when a policy uses coder, rather than module, as its domain. An attacker can supply a crafted image to evade coder-based policy restrictions, causing ImageMagick to process formats the administrator intended to block.
