CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HSummary
CVE-2026-22047 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 Exploitation for Privilege Escalation (T1068); ranked at the 25th 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 map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-22047 is a heap-buffer-overflow vulnerability in the iccDEV library, which provides tools and libraries for interacting with, manipulating, and applying International Color Consortium (ICC) color management profiles. The flaw resides in the `SIccCalcOp::Describe()` function within `IccProfLib/IccMpeCalc.cpp` and affects all versions prior to 2.3.1.2. Applications or systems that process untrusted ICC color profiles using the vulnerable iccDEV library are at risk.
Attackers can exploit this vulnerability remotely over the network with low complexity and no required privileges, though user interaction is necessary, such as convincing a user to open or process a malicious ICC profile. Successful exploitation leads to high-impact confidentiality, integrity, and availability consequences (CVSS 8.8), potentially enabling arbitrary code execution, data corruption, or denial of service via heap overflow. The issue maps to CWEs including CWE-787 (Out-of-bounds Write), CWE-252 (Unchecked Return Value), CWE-130 (Improper Handling of Length Parameter Inconsistency), and CWE-20 (Improper Input Validation).
The official patch is available in iccDEV version 2.3.1.2, as detailed in the project's GitHub security advisory (GHSA-22q7-8347-79m5), pull request #459, and issue #454. No workarounds are known, so security practitioners should prioritize upgrading affected libraries and scanning for vulnerable versions in dependent software.

Developer testing and evaluation can discover missing input validation through analysis or test cases.
SI-10 directly requires validity checks on information inputs, structurally preventing improper or missing validation.
Requiring documented development standards and tools can embed input-validation practices into the engineering process.
Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.

Secure SDLC practices directly require and enforce input validation during development.
Vulnerability scanning and recording can discover out-of-bounds write flaws so they can be remediated.
Patching or replacing vulnerable software directly eliminates known instances of this coding weakness.

Testing against a defined set of requirements and using code review plus vulnerability scanning forces validation of inputs and handling of unanticipated conditions, reducing the chance that malformed data will be accepted.
Secure-coding guidelines and mandatory security testing (including code scans) compel developers to validate and sanitize inputs at design and implementation time, lowering the incidence of malformed or malicious data reaching downstream components.
Mandating input controls that include integrity checks and input validation ensures that untrusted data is examined before use, blocking the root cause of many injection and malformed-data weaknesses.
Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.
Requiring language-specific secure coding standards, peer review, SAST and documented mitigation of common programming errors forces validation of all inputs before they are trusted.
Change management can enforce review gates that catch unsafe memory operations before deployment.
