How to fix it
CVE-2026-61863 affects imagemagick and is rated low. ImageMagick before 7.1.2-26 (and 6.x before 6.9.13-51) contains a memory leak in the TIFF encoder that occurs when a temporary file cannot be created, resulting in a small memory leak. Fix this first on internet-facing or admin systems. The practical fix is to upgrade ImageMagick to 7.1.2-26, 6.9.13-51, or a later patched release, then verify the system is no longer exposed.
- Inventory every server, container, appliance, cluster, plugin, or device that uses imagemagick.
- Check the installed version and configuration against CVE-2026-61863 and the linked advisory.
- Apply the vendor fix: upgrade ImageMagick to 7.1.2-26, 6.9.13-51, or a later patched release.
