CVE-2026-21692
📋 TL;DR
A type confusion vulnerability in iccDEV's ToXmlCurve() function allows attackers to potentially execute arbitrary code or cause denial of service by processing malicious ICC color profiles. This affects all users of iccDEV library versions prior to 2.3.1.2 who handle ICC color profiles in their applications.
💻 Affected Systems
- iccDEV library and any software using iccDEV
📦 What is this software?
Iccdev by Color
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or ransomware deployment.
Likely Case
Application crash or denial of service when processing specially crafted ICC profiles.
If Mitigated
Limited impact if proper input validation and sandboxing are implemented around ICC profile processing.
🎯 Exploit Status
Exploitation requires crafting malicious ICC profiles and getting them processed by vulnerable systems.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.1.2
Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-7662-mf46-wr88
