Summary
Adobe Photoshop Desktop on Windows and macOS contains an out-of-bounds write vulnerability (CVE-2026-95637). An attacker can execute arbitrary code in the context of the current user. Exploitation requires that a victim opens a malicious file, for example an email attachment or a downloaded design file.

- Photoshop 2025: 26.11.7 and earlier (Windows and macOS)
Fixed in
- Photoshop 2026: 27.11

Our recommendation
- Update Photoshop to 27.11 (2026) or 26.11.8 (2025) via the Creative Cloud desktop app.
- For managed environments, deploy the update using the Creative Cloud Admin Console.
- Inventory all Photoshop installations and prioritise design teams that open files from external parties.
- Until patched, avoid opening Photoshop files from unknown senders.
