CVE-2025-54211

Code execution via heap overflow during file parsing

Published Aug 12, 2025 · Updated Feb 26, 2026

Heap-based buffer overflow in Adobe InDesign 20.4, 19.5.4 and earlier allows attackers to execute code via a malicious file. Adobe identifies the failure only as a heap-based buffer overflow during malicious-file processing and has not disclosed the affected parser, file format, or faulty bounds operation. Exploitation requires a user to open the file, after which code runs with that user's privileges and can compromise the user session.
