Summary
Adobe Photoshop 2026 (27.10 and earlier) and Photoshop 2025 (26.11.7 and earlier) on Windows and macOS contain an out-of-bounds write vulnerability (CWE-787). An attacker who gets a user to open a malicious file can execute arbitrary code with the rights of the current user. No authentication is required, but user interaction is needed. Adobe is not aware of any exploits in the wild.
