It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-86423 in the wild and no public exploit code.\n\nAffected product: Imagemagick Imagemagick. 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-2026-86423/ (Markdown: https://insights.sbomify.com/CVE-2026-86423/index.md)","id":"CVE-2026-86423","markdown":"https://insights.sbomify.com/CVE-2026-86423/index.md","name":"CVE-2026-86423","record":{"aliases":["DEBIAN-CVE-2026-86423","ECHO-469c-b2a9-e51b","GHSA-5m9j-96ff-j6qc","GHSA-g684-8gxh-c62w","MINI-4hh9-p85v-wwgg","UBUNTU-CVE-2026-86423"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ImageMagick library","requires_auth":"none","summary":"A crafted call to GetList in PerlMagick triggers a heap-use-after-free, causing a crash and denial of service.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"imagemagick","vendor":"imagemagick"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"ImageMagick before 7.1.2-30 and 6.9.x before 6.9.13-55 contains a heap-use-after-free vulnerability in the GetList method of PerlMagick.
