CVE-2026-61861

Estado: AnalizadaMedia (6.3)—

ImageMagick before 7.1.2-26 contains a use-after-free vulnerability in the FormatMagickCaption method when memory allocation fails. Attackers can trigger memory allocation failures to cause a dangling pointer to reference freed memory, potentially enabling denial of service or code execution.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
