CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2026-21507 is a high-severity Infinite Loop (CWE-835) vulnerability in Color Iccdev. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 31th 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-2 (Flaw Remediation) — 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-2026-21507 affects iccDEV, a set of libraries and tools for working with ICC color management profiles. Versions 2.3.1 and prior contain an infinite loop vulnerability in the CalcProfileID function within IccProfile.cpp, classified under CWE-835 (Loop with Unreachable Exit Condition). The issue received a CVSS v3.1 base score of 7.5, reflecting high severity due to its potential for denial-of-service impact.
A remote, unauthenticated attacker with network access can exploit this vulnerability with low complexity and no user interaction required. By providing a specially crafted ICC profile that triggers the infinite loop during profile ID calculation, the attacker can cause the affected iccDEV component to hang or consume excessive resources, resulting in high availability disruption (A:H) with no impact on confidentiality or integrity.
Mitigation is available via an official patch in iccDEV version 2.3.1.1, as detailed in the project's GitHub security advisory (GHSA-hgp5-r8m9-8qpj), issue tracker (#244), and the fixing commit (3f3ce789d0d2b608c194ed172fa38943519dc198). Security practitioners should prioritize updating to the patched version and validate ICC profiles processed by iccDEV in affected environments.

Developer testing and evaluation can discover unreachable loop exit conditions through static analysis, fuzzing, or execution tracing.
Flaw remediation processes identify and correct infinite-loop defects reported from testing or operations.
Requiring documented development processes and secure coding standards reduces introduction of loops whose termination conditions are unreachable.

Security testing can uncover infinite-loop conditions before release.
Secure development life cycle mandates practices that can detect and prevent infinite-loop defects.
Application security requirements can specify loop-termination rules, indirectly reducing the weakness.
Secure coding standards directly address loop termination and prevent infinite loops.
Secure architecture principles encourage designs that avoid unreachable exit conditions.
Change management can require review of loop logic when code is modified.
