CVE-2026-25796: ImageMagick

High severity, CVSS 7.5. EPSS: 0.5% chance of exploitation in the next 30 days.

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, in `ReadSTEGANOImage()` (`coders/stegano.c`), the `watermark` Image object is not freed on three early-return paths, resulting in a definite memory leak (~13.5KB+ per invocation) that can be exploited for denial of service. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

Affected products

• ImageMagick ImageMagick: before 6.9.13-40 (fixed in 6.9.13-40); from 7.0.0-0, before 7.1.2-15 (fixed in 7.1.2-15)
