CVE-2026-96521 · Severity: high · CVSS 7.8 · Published 2026-10-13

Adobe Photoshop is a professional image editing application used by designers and photographers to create and manipulate digital content. Multiple out-of-bounds write vulnerabilities allow attackers to execute arbitrary code on a user's computer by tricking them into opening a malicious image file. An attacker exploiting this could gain full control of the affected system under the current user's permissions.
