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-2026-86550 in the wild and no public exploit code.\n\nAffected product: ZTE NebulaOS. 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-2026-86550/ (Markdown: https://insights.sbomify.com/CVE-2026-86550/index.md)","id":"CVE-2026-86550","markdown":"https://insights.sbomify.com/CVE-2026-86550/index.md","name":"CVE-2026-86550","record":{"aliases":["GHSA-5xg9-xgmv-w59x"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"ZTE NebulaOS browser","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in any website's origin via a UXSS flaw in the ZTE NebulaOS browser, compromising user sessions and data.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zte","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"NuBrowser lacks protocol whitelist validation for the S.browser_fallback_url field of intent://, allowing attackers to inject javascript: URLs via 302 redirects.
