CVE-2025-43589

Code execution via malicious-file use-after-free

Published Jun 10, 2025 · Updated Feb 26, 2026

Use-after-free in Adobe InDesign ID20.2 and earlier or ID19.5.3 and earlier allows attackers to execute code through a malicious file. Adobe identifies only a memory-lifetime error and has not published the affected parser, object type, or invalid reuse operation. Exploitation requires a local user to open the crafted file, after which code runs with that user's privileges and can read, change, or disrupt accessible data and processes.
