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-2025-58146 in the wild and no public exploit code.\n\nAffected product: Xen XAPI. 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-2025-58146/ (Markdown: https://insights.sbomify.com/CVE-2025-58146/index.md)","id":"CVE-2025-58146","markdown":"https://insights.sbomify.com/CVE-2025-58146/index.md","name":"CVE-2025-58146","record":{"aliases":["GHSA-cfmg-797f-j883"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Xen XAPI","requires_auth":"none","summary":"Improper UTF-8 handling and missing sanitization in Xen XAPI can crash the event thread or corrupt the database, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"XEN","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"There are multiple issues.\n\n 1.

XAPI's UTF-8 encoder implements v3.0 of the Unicode spec, but XAPI\n    uses libraries which conform to the stricter v3.1 of the Unicode\n    spec.
