CVE-2022-28274
📋 TL;DR
Adobe Photoshop versions 22.5.6 and earlier and 23.2.2 and earlier contain an out-of-bounds read vulnerability when parsing malicious files. An attacker could exploit this to execute arbitrary code in the context of the current user. This affects users who open untrusted Photoshop files.
💻 Affected Systems
- Adobe Photoshop
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise through arbitrary code execution with current user privileges, potentially leading to data theft, ransomware deployment, or lateral movement.
Likely Case
Application crash or limited information disclosure from memory reads, with potential for code execution if combined with other vulnerabilities.
If Mitigated
No impact if users don't open untrusted files or if application is patched.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) and memory manipulation techniques.
🛠️ Fix & Mitigation
✅ Official Fix

Restrict file opening
allConfigure Photoshop to only open files from trusted sources or disable automatic file opening.
Application control
windowsUse application whitelisting to restrict Photoshop execution to trusted locations only.
🧯 If You Can't Patch
- Implement strict user training about opening untrusted Photoshop files
- Use sandboxing or virtualization for Photoshop when handling untrusted files
🔍 How to Verify
Check if Vulnerable:
Check Photoshop version via Help > About Photoshop. If version is 22.5.6 or earlier, or 23.2.2 or earlier, system is vulnerable.Check Version:
On Windows: wmic product where name="Adobe Photoshop" get version
On macOS: /Applications/Adobe\ Photoshop\ */Adobe\ Photoshop.app/Contents/Info.plist | grep -A1 CFBundleShortVersionStringVerify Fix Applied:
Verify Photoshop version is 22.5.7 or later for version 22.x, or 23.3 or later for version 23.x.📡 Detection & Monitoring
