It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-91734 in the wild and no public exploit code.\n\nAffected product: Google Chrome. 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-2026-91734/ (Markdown: https://insights.sbomify.com/CVE-2026-91734/index.md)","id":"CVE-2026-91734","markdown":"https://insights.sbomify.com/CVE-2026-91734/index.md","name":"CVE-2026-91734","record":{"aliases":["DEBIAN-CVE-2026-91734","ECHO-e36b-c85b-95fd","GHSA-p2gj-6m34-2678","MINI-v286-qc8j-57r4"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Google Chrome","requires_auth":"none","summary":"A local attacker can execute arbitrary code outside the sandbox due to incorrect authorization in Chrome on Windows.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"chrome","vendor":"google"}],"cvss":{"score":7.4,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Incorrect authorization in Core in Google Chrome on on Windows prior to 153.0.8010.47 allowed a local attacker to execute arbitrary code outside the sandbox via a local program.
