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-2026-118245/ (Markdown: https://insights.sbomify.com/CVE-2026-118245/index.md)","id":"CVE-2026-118245","markdown":"https://insights.sbomify.com/CVE-2026-118245/index.md","name":"CVE-2026-118245","record":{"aliases":["GHSA-grj7-r4jv-pw9j"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Highcharts JS is a JavaScript charting library based on SVG. From 1.0.0 until 4.2.2, Highcharts Dashboards uses chartConstructor as an unchecked property lookup in the Highcharts namespace and invokes the selected member with the component container and chartOptions. An attacker who controls dashboard configuration can select a public utility function instead of a supported chart constructor, causing attacker-controlled options to be copied to the container as properties or attributes. Markup and event handlers can then execute in the hosting page origin when the board renders. No user interaction beyond rendering the board is required.
