Adobe Photoshop: Out-of-bounds write allows arbitrary code execution
Summary
Adobe Photoshop Desktop on Windows and macOS contains an out-of-bounds write (CWE-787) that can lead to arbitrary code execution. An attacker can run code in the context of the logged-in user by convincing a victim to open a malicious file. No network exposure is involved, but user interaction is required.
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
- No vendor-documented workaround. Installing the update is the fix.
- Until patched (general guidance, not from a vendor source): do not open image or project files from untrusted senders or unknown downloads, and restrict local administrator rights.
Exploitation
- Adobe is not aware of any exploits in the wild for the issues in this update.
- ZDI lists the Photoshop bulletin APSB26-158 with Exploited: No.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
- No public proof of concept found.
Our recommendation
- Update Photoshop to 27.11 (2026) or 26.11.8 (2025) via the Creative Cloud desktop app or the Admin Console.
- Check your installed Photoshop versions and prioritise machines used for opening files from external sources.
- Warn staff about opening unexpected image or project files from email or downloads.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
