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-2026-44698 in the wild and no public exploit code.\n\nAffected product: Home Assistant Companion app (Android). 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-2026-44698/ (Markdown: https://insights.sbomify.com/CVE-2026-44698/index.md)","id":"CVE-2026-44698","markdown":"https://insights.sbomify.com/CVE-2026-44698/index.md","name":"CVE-2026-44698","record":{"aliases":["GHSA-7jp2-p2fw-mgvf"],"analysis":{"component_type":"mobile_application","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Home Assistant Companion app","requires_auth":"none","summary":"Attackers can inject JavaScript via cross-origin iframes to steal user access tokens in Home Assistant mobile apps.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-940","name":"Improper Verification of Source of a Communication Channel"},{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-749","name":"Exposed Dangerous Method or Function"},{"id":"CWE-346","name":"Origin Validation Error"}],"description":"Home Assistant is open source home automation software that puts local control and privacy first. Prior to 2026.4.1 for iOS and 2026.4.4 for Android, he Home Assistant Companion apps for Android and iOS expose a JavaScript bridge to the in-app WebView window.externalApp on Android and webkit.messageHandlers.getExternalAuth (alongside revokeExternalAuth and externalBus) on iOS. Two flaws expose the bridge to all frames (including cross-origin iframes) and unsanitized interpolation of the JavaScript callback identifier allows a cross-origin iframe rendered inside the Companion app to execute arbitrary JavaScript in the Home Assistant frontend's main-frame origin and exfiltrate the signed-in user's access token. This vulnerability is fixed in 2026.4.1 for iOS and 2026.4.4 for Android.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Home Assistant: Cross-origin iframe access token exfiltration via WebView JS bridge callback injection","id":"CVE-2026-44698","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"LibJWT: Algorithm confusion allows JWT forgery with RSA JWK as empty-key HMAC","id":"CVE-2026-44699"},"packages":[],"prev":{"headline":"Klever-Go MultiDataInterceptor: remote OOM via crafted compressed P2P payload","id":"CVE-2026-44697"},"products":["Companion app (Android)","Companion app (iOS)","core"],"published":"2026-05-29","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-29","vendors":["Home Assistant","home-assistant"]},"summary":"Attackers can inject JavaScript via cross-origin iframes to steal user access tokens in Home Assistant mobile apps.","url":"https://insights.sbomify.com/CVE-2026-44698/"}
