Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-53453 in the wild and no public exploit code.\n\nAffected product: ha-china blueprint-studio. 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-2026-53453/ (Markdown: https://insights.sbomify.com/CVE-2026-53453/index.md)","id":"CVE-2026-53453","markdown":"https://insights.sbomify.com/CVE-2026-53453/index.md","name":"CVE-2026-53453","record":{"aliases":["GHSA-ppwq-ch6x-936g"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Home Assistant plugin","requires_auth":"low_privilege","summary":"Non-admin users can bypass authorization to execute services, modify files, and access sensitive data in Blueprint Studio.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Blueprint Studio is a VS Code-like file editor for Home Assistant configuration files. Prior to 2.5.2, Blueprint Studio exposed administrator-intended backend API actions to any authenticated Home Assistant user because the backend did not consistently enforce the panel's admin-only authorization boundary. Affected surfaces included the backend API, upload API, stream routes, terminal WebSocket, Blueprint Studio WebSocket subscriptions, call_service, render_template, global_replace, file and stream access paths, upload handling, and terminal helpers. A non-admin user could invoke arbitrary Home Assistant services, expose Home Assistant state through templates, modify configuration files, access streamed or downloaded configuration content, upload files, or reach terminal-related helpers. These actions could compromise the confidentiality, integrity, and availability of the Home Assistant installation. This issue is fixed in version 2.5.2.","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":"Blueprint Studio API authorization bypass for non-admin Home Assistant users","id":"CVE-2026-53453","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Blueprint Studio stored Git credentials in plaintext Git credential store","id":"CVE-2026-53454"},"packages":[],"prev":{"headline":"Ground Station: Unauthenticated out-of-containment file read via `sigmfplayback` `recordingPath`","id":"CVE-2026-53452"},"products":["blueprint-studio"],"published":"2026-08-18","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":"2026-08-19","vendors":["ha-china"]},"summary":"Non-admin users can bypass authorization to execute services, modify files, and access sensitive data in Blueprint Studio.","url":"https://insights.sbomify.com/CVE-2026-53453/"}
