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-2026-118244/ (Markdown: https://insights.sbomify.com/CVE-2026-118244/index.md)","id":"CVE-2026-118244","markdown":"https://insights.sbomify.com/CVE-2026-118244/index.md","name":"CVE-2026-118244","record":{"aliases":["GHSA-65hg-cf3f-5m39"],"analysis":null,"analysis_generated_by":null,"assigner":"GitHub_M","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/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 12.0.0 until 12.6.1 and 13.1.0, Highcharts falls back to assigning raw markup to innerHTML when DOMParser cannot return a document, before its allow-list is applied. In Chromium, the Trusted Types callback can throw while a beforeprint handler runs, so a page that redraws a chart during beforeprint can insert untrusted HTML text options into the hosting document. Event handlers in that markup then run in the page origin when printing begins. The issue affects HTML-rendered titles, labels, data labels, responsive text, and the Stock, Maps, and Gantt products shipped in the same package. This issue is fixed in 12.6.1 and 13.1.0.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Highcharts Core: AST `DOMParser` fallback assigns unsanitized markup to `innerHTML` during print","id":"CVE-2026-118244","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"Highcharts Dashboards: `chartConstructor` is an unchecked lookup into the Highcharts namespace","id":"CVE-2026-118245"},"packages":[{"ecosystem":"npm","fixed":["12.6.1"],"introduced":["12.0.0"],"last_affected":[],"package":"highcharts","purl":null,"source":"GHSA-65hg-cf3f-5m39"},{"ecosystem":"npm","fixed":["12.6.1"],"introduced":["12.0.0"],"last_affected":[],"package":"highcharts","purl":"pkg:npm/highcharts","source":"GHSA-65hg-cf3f-5m39"},{"ecosystem":"npm","fixed":["13.1.0"],"introduced":["13.0.0"],"last_affected":[],"package":"highcharts","purl":null,"source":"GHSA-65hg-cf3f-5m39"},{"ecosystem":"npm","fixed":["13.1.0"],"introduced":["13.0.0"],"last_affected":[],"package":"highcharts","purl":"pkg:npm/highcharts","source":"GHSA-65hg-cf3f-5m39"}],"prev":{"headline":"Highcharts Dashboards: `__proto__` data table id writes sync listeners to `Object.prototype`","id":"CVE-2026-118243"},"products":["highcharts"],"published":"2026-10-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-28","vendors":["highcharts"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-118244/"}
