CVE-2024-47061
📋 TL;DR
CVE-2024-47061 is a security vulnerability in Plate JavaScript toolkit that allows malicious actors to inject custom DOM attributes, potentially leading to cross-site scripting (XSS) attacks and information exposure. The vulnerability affects all Plate editors using affected versions of @udecode/plate-core that allow custom attributes through the nodeProps prop. Attackers could steal user data, execute arbitrary code, or leak IP addresses through crafted attributes.
💻 Affected Systems
- @udecode/plate-core
- Plate JavaScript toolkit
- Applications using Plate with Slate text editors

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of user sessions via XSS leading to data theft, account takeover, and malware distribution through the text editor interface.
Likely Case
Information leakage of user IP addresses and document access patterns to malicious third parties via crafted attributes that trigger web requests.
If Mitigated
Limited impact with proper content security policies, input validation, and attribute filtering in place.
🎯 Exploit Status
Exploitation requires ability to inject malicious attributes into Plate editor content. Most vulnerable attributes are href and src on <a> and <iframe> elements when nodeProps are spread without validation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Patched versions of @udecode/plate-core (specific version numbers not provided in advisory)
Vendor Advisory: https://github.com/udecode/plate/security/advisories/GHSA-73rg-f94j-xvhx
Restart Required: No
Instructions:
1. Upgrade to patched versions of @udecode/plate-core. 2. Review and test custom attribute handling. 3. If breaking changes occur, selectively re-enable only safe attributes using plugin configuration.
🔧 Temporary Workarounds
Manual patch with patch-package
allApply security patch without upgrading entire package
npx patch-package @udecode/plate-core
Follow patch creation process to remove attribute logic
Yarn patch
allUse yarn's patch functionality to modify vulnerable code
yarn patch @udecode/plate-core
Edit package to remove attribute injection logic
🧯 If You Can't Patch
- Implement strict content security policies (CSP) to block inline scripts and unsafe attributes
- Add server-side validation to sanitize all user input before processing in Plate editor
🔍 How to Verify
Check if Vulnerable:
Check package.json for @udecode/plate-core version and review if custom attributes are enabled in Plate configurationCheck Version:
npm list @udecode/plate-core or check package.jsonVerify Fix Applied:
Verify upgraded package version and test that malicious attributes (href, src, style with URLs) are blocked📡 Detection & Monitoring
