Adobe Photoshop: Integer overflow allows code execution via malicious file
Summary
Adobe Photoshop Desktop contains an integer overflow (wraparound) vulnerability, tracked as CVE-2026-95636. An attacker can use a crafted file to execute arbitrary code in the context of the current user. Exploitation requires that a victim opens the malicious file in Photoshop.
Affected
- Photoshop 2026: 27.10 and earlier (Windows and macOS)
- Photoshop 2025: 26.11.7 and earlier (Windows and macOS)
Fixed in
- Photoshop 2026: 27.11
- Photoshop 2025: 26.11.8
Workaround
Unknown.
Exploitation
- Adobe is not aware of any exploits in the wild for the issues in APSB26-158.
- No public proof of concept was found at the time of writing.
- CISA SSVC assessment: exploitation none, automatable no, technical impact total.
Our recommendation
- Update Photoshop 2025 to 26.11.8 and Photoshop 2026 to 27.11 via the Creative Cloud desktop app or the Admin Console.
- Verify the installed versions on all workstations.
- Until patched, only open image files from trusted senders and avoid unexpected file types, such as DICOM files, in Photoshop.
- Treat this as a standard patch-cycle item, not an emergency, unless there is evidence of active exploitation.
