CVE-2025-43592

Arbitrary code execution via uninitialized pointer access

Published Jul 8, 2025 · Updated Feb 26, 2026

Uninitialized pointer access in Adobe InDesign 19.5.3 and earlier allows attackers to execute code through a malicious file. The application accesses an uninitialized pointer while opening the file, but Adobe has not disclosed the affected parser or code path. Execution occurs in the current user's context and requires that user to open the crafted document, enabling data access, modification, or application disruption.
