Adobe Photoshop: Out-of-bounds write allows arbitrary code execution
Summary
An out-of-bounds write flaw in Adobe Photoshop Desktop allows an attacker to execute arbitrary code in the context of the current user. Exploitation requires a victim to open a malicious file, and no privileges are needed. Successful exploitation could fully compromise the user's session and data.
Affected
- Adobe Photoshop 2026 (27.11 and earlier, Windows and macOS)
- Adobe Photoshop 2025 (26.11.8 and earlier, Windows and macOS)
- The CVE record lists affected ranges up to 26.11.8 and up to 27.11; the vendor bulletin was not accessible for verification.
Fixed in
- Adobe Photoshop 2026: 27.11.1 (per CVE record and bulletin summary; to be verified against APSB26-181)
- Adobe Photoshop 2027: 28.0
- Adobe Photoshop 2025: no further update planned; move to Photoshop 2026 27.11.1 or Photoshop 2027 28.0
Workaround
Unknown.
Exploitation
- Adobe is not aware of any exploits in the wild for the issues in APSB26-181.
- Not listed in CISA KEV at the time of research.
- No public proof-of-concept indexed at publication; the CVE was published on 2026-11-10 and data may change.
Our recommendation
- Update Photoshop to the fixed build via the Creative Cloud desktop app or the Admin Console on all endpoints.
- Prioritise machines that regularly open files from external sources, such as clients, email or downloads.
- Restrict opening Photoshop files from unknown senders.
- Run Photoshop without local administrator rights to limit the impact of code execution.
- Re-check the CVE and the Adobe advisory once NVD analysis is complete.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
