CVE-2026-24410 is a vulnerability in the InternationalColorConsortium's iccDEV library, specifically in versions 2.3.1.1 and earlier. The root cause is improper input validation (CWE-20) in the CIccProfileXml::ParseBasic() function, which processes ICC color management profiles. When user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs, it can cause undefined behavior and null pointer dereferences (CWE-476, CWE-690, CWE-758). This can be exploited by an attacker who crafts malicious ICC profiles or binary blobs that, when parsed by vulnerable versions of iccDEV, can cause application crashes (denial of service), manipulation of data, bypassing of application logic, and potentially arbitrary code execution. The vulnerability is remotely exploitable over a network (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R), such as opening or processing a malicious file. The scope is unchanged (S:U), and the impact affects integrity and availability but not confidentiality (C:N/I:L/A:H). The CVSS v3.1 base score is 7.1, indicating a high severity. No known exploits have been reported in the wild as of the publication date (January 24, 2026). The issue has been addressed in iccDEV version 2.3.1.2, which includes proper input validation to prevent unsafe processing of ICC profiles.

For European organizations, the impact of CVE-2026-24410 can be significant, especially for those in sectors that rely heavily on color management workflows, such as printing, publishing, graphic design, photography, and manufacturing industries involving color-critical processes. Exploitation could lead to denial of service, disrupting business operations and causing downtime. More critically, the ability to manipulate data or bypass application logic could undermine the integrity of color profiles, leading to incorrect color rendering or printing errors, which can affect product quality and brand reputation. In worst-case scenarios, remote code execution could allow attackers to gain a foothold in affected systems, potentially leading to broader network compromise. Given the network attack vector and lack of required privileges, attackers could target exposed services or trick users into opening malicious files, increasing the risk of widespread impact. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time. Organizations with automated workflows that ingest ICC profiles from external sources are particularly vulnerable to supply chain or targeted attacks.

European organizations should immediately upgrade all instances of iccDEV to version 2.3.1.2 or later to ensure the vulnerability is patched. Where upgrading is not immediately feasible, implement strict input validation and sanitization controls on any ICC profile data or binary blobs before processing. Employ network-level protections such as firewalls and intrusion detection systems to monitor and block suspicious traffic that may deliver malicious ICC profiles. Educate users and administrators about the risks of opening untrusted or unsolicited ICC profile files, especially those received via email or downloaded from unverified sources. Integrate file integrity monitoring and application whitelisting to detect and prevent unauthorized modifications or execution of malicious code. For organizations using automated pipelines that process ICC profiles, introduce sandboxing or isolated environments to analyze and validate profiles before production use. Maintain up-to-date backups and incident response plans to quickly recover from potential denial of service or compromise events. Collaborate with software vendors and security communities to stay informed about emerging exploits or related vulnerabilities in color management libraries.
