CVE-2026-21674: iccDEV has a Memory Leak in its CIccProfileXml::ParseTag() Error Path

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Versions 2.3.1 and below contain a memory leak vulnerability in its XML MPE Parsing Path (iccFromXml). This issue is fixed in version 2.3.1.1.

Security readout for executives and security teams

Plain-English summary

CVE-2026-21674 is a low-severity memory leak in iccDEV, a toolkit for ICC color profile handling. Affected versions before 2.3.1.1 can leak memory when parsing certain XML profile data through an error path. The main business risk is limited availability impact, not data theft or system takeover.

Executive priority

Treat as routine patching unless iccDEV processes untrusted profile files at scale. Prioritize upgrade in image, print, color-management, or file-processing environments where repeated malformed inputs could affect service availability.

Technical view

iccDEV versions below 2.3.1.1 contain a CWE-401 memory leak in CIccProfileXml::ParseTag() within the XML MPE parsing path, referenced as iccFromXml. CVSS 3.1 is 3.3: local attack vector, low complexity, no privileges, user interaction required, and low availability impact only.

Likely exposure

Exposure is most relevant where iccDEV or tools built on it parse XML ICC profiles, especially files received from users or external workflows. Systems not using iccDEV, or not invoking XML profile parsing, are unlikely to be affected.

Exploitation context

The provided sources do not report active exploitation, and the CVE is not in KEV. The CVSS vector indicates exploitation requires local access and user interaction. Impact is described as memory leakage causing limited availability degradation.

Researcher notes

Evidence points to an error-path leak in CIccProfileXml::ParseTag(). The public bundle identifies the fix version and commit but does not provide evidence of exploitation in the wild. Analysis should focus on reachability through XML profile parsing and dependency embedding.

Mitigation direction

  • Upgrade iccDEV to version 2.3.1.1 or later.
  • Identify applications or pipelines that bundle or link iccDEV.
  • Restrict processing of untrusted XML ICC profiles where upgrade is delayed.
  • Monitor the GitHub advisory and vendor repository for additional guidance.

Validation and detection

  • Check installed or bundled iccDEV versions are 2.3.1.1 or later.
  • Review dependency manifests and build artifacts for iccDEV usage.
  • Confirm whether iccFromXml or XML MPE parsing is reachable in production workflows.
  • Track remediation against the vendor advisory and fixing commit.
