Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-27648 in the wild and no public exploit code.\n\nAffected product: OpenHarmony. 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-2026-27648/ (Markdown: https://insights.sbomify.com/CVE-2026-27648/index.md)","id":"CVE-2026-27648","markdown":"https://insights.sbomify.com/CVE-2026-27648/index.md","name":"CVE-2026-27648","record":{"aliases":["GHSA-fpp4-pf9w-p6rr"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenHarmony OS","requires_auth":"low_privilege","summary":"A remote attacker can achieve arbitrary code execution in pre-installed apps via an out-of-bounds write in the web_webview component.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OpenHarmony","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"in OpenHarmony v6.0 and prior versions allow a remote attacker arbitrary code execution in pre-installed apps.","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":"web_webview has an out-of-bounds write vulnerability","id":"CVE-2026-27648","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"CTEK Chargeportal Insufficient Session Expiration","id":"CVE-2026-27649"},"packages":[],"prev":{"headline":"Mobility46 mobility46.se Insufficient Session Expiration","id":"CVE-2026-27647"},"products":["OpenHarmony"],"published":"2026-05-19","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":"2026-05-19","vendors":["OpenHarmony"]},"summary":"A remote attacker can achieve arbitrary code execution in pre-installed apps via an out-of-bounds write in the web_webview component.","url":"https://insights.sbomify.com/CVE-2026-27648/"}
