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-2026-73537 in the wild and no public exploit code.\n\nAffected product: Japan Science and Technology Agency (JST) Miraikan Assist App Android version. 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-2026-73537/ (Markdown: https://insights.sbomify.com/CVE-2026-73537/index.md)","id":"CVE-2026-73537","markdown":"https://insights.sbomify.com/CVE-2026-73537/index.md","name":"CVE-2026-73537","record":{"aliases":["GHSA-599w-xgxp-wr28"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Miraikan Assist App","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in the app's WebView, altering displayed content for users of the Miraikan Assist App.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:N/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross-site scripting vulnerability exists in Miraikan Assist App. If this vulnerability is exploited, an arbitrary script may be executed in the browser component (WebView) running on the affected product, resulting in the displayed content being altered.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cross-site scripting in Miraikan Assist App Android version","id":"CVE-2026-73537","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Gitea external renderer argument injection and code execution","id":"CVE-2026-73539"},"packages":[],"prev":{"headline":"Gitea second-factor bypass through OpenID identity linking","id":"CVE-2026-73535"},"products":["Miraikan Assist App Android version","Miraikan Assist App iOS version"],"published":"2026-08-21","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-21","vendors":["Japan Science and Technology Agency (JST)"]},"summary":"Attackers can execute arbitrary scripts in the app's WebView, altering displayed content for users of the Miraikan Assist App.","url":"https://insights.sbomify.com/CVE-2026-73537/"}
