CVE-2026-23876: ImageMagick

Critical severity, CVSS 9.8. EPSS: 0.7% 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 7.1.2-13 and 6.9.13-38, a heap buffer overflow vulnerability in the XBM image decoder (ReadXBMImage) allows an attacker to write controlled data past the allocated heap buffer when processing a maliciously crafted image file. Any operation that reads or identifies an image can trigger the overflow, making it exploitable via common image upload and processing pipelines. Versions 7.1.2-13 and 6.9.13-38 fix the issue.

Affected products

• ImageMagick ImageMagick: before 6.9.13-38 (fixed in 6.9.13-38); from 7.0.0-0, before 7.1.2-13 (fixed in 7.1.2-13)
