No official patch exists; remove or replace node-twain with alternative solutions.
🔧 Temporary Workarounds
Input Validation Wrapper
allImplement custom validation to restrict string lengths for productName, productFamily, manufacturer, and version.info to < 34 characters before passing to node-twain.
🧯 If You Can't Patch
- Discontinue use of node-twain and migrate to alternative TWAIN libraries.
- Implement network segmentation to isolate systems using node-twain from critical assets.
