CVE-2026-48734

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-49 and 7.1.2-24, a crafted MVG file could result in a stack overflow due to a missing depth or visited-set check. This issue has been patched in versions 6.9.13-49 and 7.1.2-24.

Use ImageMagick to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.
