An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-21691 in the wild and no public exploit code.\n\nAffected product: Color Iccdev. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-21691/ (Markdown: https://insights.sbomify.com/CVE-2026-21691/index.md)","id":"CVE-2026-21691","markdown":"https://insights.sbomify.com/CVE-2026-21691/index.md","name":"CVE-2026-21691","record":{"aliases":["GHSA-c9q5-x498-jv92"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ICC color management library","requires_auth":"none","summary":"A type confusion vulnerability in the iccDEV library allows attackers to cause memory corruption and potential code execution when processing malicious ICC color profiles.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"iccdev","vendor":"color"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"},{"id":"CWE-697","name":"Incorrect Comparison"},{"id":"CWE-476","name":"NULL Pointer Dereference"},{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-140","name":"Improper Neutralization of Delimiters"},{"id":"CWE-1025","name":"Comparison Using Wrong Factors"}],"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.
