It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-0555 exists.\n\nAffected product: Microsoft Windows 10. 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-2019-0555/ (Markdown: https://insights.sbomify.com/CVE-2019-0555/index.md)","id":"CVE-2019-0555","markdown":"https://insights.sbomify.com/CVE-2019-0555/index.md","name":"CVE-2019-0555","record":{"aliases":["GHSA-x49p-2wmh-gxv5"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows OS","requires_auth":"low_privilege","summary":"An attacker can escape the browser AppContainer sandbox to gain elevated privileges on affected Windows systems.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"windows_10","vendor":"microsoft"},{"product":"windows_8.1","vendor":"microsoft"},{"product":"windows_rt_8.1","vendor":"microsoft"},{"product":"windows_server_2012","vendor":"microsoft"},{"product":"windows_server_2016","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"An elevation of privilege vulnerability exists in the Microsoft XmlDocument class that could allow an attacker to escape from the AppContainer sandbox in the browser, aka \"Microsoft XmlDocument Elevation of Privilege Vulnerability.\" This affects Windows Server 2012 R2, Windows RT 8.1, Windows Server 2012, Windows Server 2019, Windows Server 2016, Windows 8.1, Windows 10, Windows 10 Servers.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2019-01-16","github_poc":1,"max_poc_stars":5,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-08-03T01:53:27Z","kind":"github_poc","ref":"https://github.com/kai6u/TriBell_Edge_SandBox_Escape","stars":5,"title":"Tribell Edge Sandbox Escape - PoCs of Edge's legacy vulnerabilities BadgeUpdateManager / TileFlyoutUpdateManager / ToastNotificationManager to exploit cross-boundary XmlDocument sharing and escape Edge’s LPAC sandbox (CVE-2019-0555).
