CVE-2026-21280

Estado: AnalizadaAlta (8.6)—

Illustrator versions 29.8.3, 30.0 and earlier are affected by an Untrusted Search Path vulnerability that could result in arbitrary code execution in the context of the current user. If the application uses a search path to locate critical resources such as programs, an attacker could modify that search path to point to a malicious program, which the targeted application would then execute. Exploitation of this issue requires user interaction in that a victim must open a malicious file and scope is changed.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Puntuación base: 8.6

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.25%
Percentil entre todas las CVEs puntuadas: 15
Fecha de la puntuación: 6/10/2026

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).
