CVE-2026-22255
Published: 08 January 2026
Summary
CVE-2026-22255 is a high-severity Improper Input Validation (CWE-20) vulnerability in Color Iccdev. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Malicious File (T1204.002); ranked at the 18.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly requires timely patching of the iccDEV library to version 2.3.1.2, which contains the fix for the heap-buffer-overflow vulnerability.
Provides memory protections like ASLR, DEP, and stack canaries that prevent successful exploitation of the heap buffer overflow even if unpatched.
Mandates input validation for ICC profiles to address the improper input validation (CWE-20) root cause before processing in the vulnerable CIccCLUT::Init() function.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Heap buffer overflow in ICC profile parser enables RCE via malicious file supplied to vulnerable application/library.
NVD Description
iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of International Color Consortium (ICC) color management profiles. Versions prior to 2.3.1.2 have a heap-buffer-overflow vulnerability in `CIccCLUT::Init()` at `IccProfLib/IccTagLut.cpp`. This vulnerability affects users…

of the iccDEV library who process ICC color profiles. Version 2.3.1.2 contains a patch. No known workarounds are available.
Deeper analysisAI
CVE-2026-22255 is a heap-buffer-overflow vulnerability in the iccDEV library, which provides a set of libraries and tools for interacting with, manipulating, and applying International Color Consortium (ICC) color management profiles. The flaw resides in the `CIccCLUT::Init()` function at `IccProfLib/IccTagLut.cpp` and affects all versions prior to 2.3.1.2. It impacts users of the iccDEV library who process ICC color profiles, with associated CWEs including CWE-20 (Improper Input Validation), CWE-130 (Improper Handling of Length Parameter Inconsistency), and CWE-252 (Unchecked Return Value).
The vulnerability carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), indicating high severity. An unauthenticated network attacker can exploit it by tricking a user into processing a specially crafted malicious ICC profile, triggering the heap buffer overflow. Successful exploitation enables high-impact outcomes, including unauthorized disclosure of confidential information, modification of data or code integrity, and disruption of availability.
The patch is available in iccDEV version 2.3.1.2, as detailed in the project's GitHub security advisory (GHSA-qv2w-mq3g-73gv), issue tracker (#466), and pull request (#469). No known workarounds exist.
