CVE-2026-61864 ImageMagick CVE debrief

A memory leak vulnerability exists in ImageMagick before versions 7.1.2-26 and 6.9.13-51. The vulnerability occurs when a color transformation to the log colorspace fails, resulting in a small amount of memory not being released. This issue could potentially lead to a denial of service (DoS) attack if exploited. Defenders responsible for maintaining ImageMagick installations should assess the potential impact of this vulnerability on their systems and prioritize verification and remediation efforts. The CVE record and NVD entry provide information on the vulnerability, but details on exploitation, impact, and remediation are limited. Affected product deployments should be confirmed
