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-2026-107448 exists.\n\nAffected product: Wizards of the Coast Magic: The Gathering Arena. 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-2026-107448/ (Markdown: https://insights.sbomify.com/CVE-2026-107448/index.md)","id":"CVE-2026-107448","markdown":"https://insights.sbomify.com/CVE-2026-107448/index.md","name":"CVE-2026-107448","record":{"aliases":["GHSA-25hq-wqc9-cgfc"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MTG Arena client","requires_auth":"none","summary":"Attackers controlling server content can invoke arbitrary URI handlers on client machines, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":3.4,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-99","name":"Improper Control of Resource Identifiers"}],"description":"Magic: The Gathering Arena (Windows/Steam client; 2026.59.30.12801.127931.6 and certain later 2026.60.x builds) passes a server-supplied URL from a home-screen carousel GoToExternalUrl action directly to the Windows shell via Application.OpenURL/ShellExecuteW without validating the URI scheme or domain.
