Technical details

An out-of-bounds write vulnerability (CWE-787) exists in Adobe Illustrator Desktop versions 2025 and 2026. The flaw is triggered when the application processes a specially crafted file, leading to memory corruption. An attacker can leverage this to execute arbitrary code in the context of the current user. Exploitation requires local delivery of a malicious file and user interaction (opening the file). Adobe has released patches in versions 30.6 (for 2026) and 29.8.9 (for 2025) to address this issue.
