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-2025-8321 in the wild and no public exploit code.\n\nAffected product: Tesla Wall Connector. 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-2025-8321/ (Markdown: https://insights.sbomify.com/CVE-2025-8321/index.md)","id":"CVE-2025-8321","markdown":"https://insights.sbomify.com/CVE-2025-8321/index.md","name":"CVE-2025-8321","record":{"aliases":["GHSA-mccj-pq5m-h2mp"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"EV charging station","requires_auth":"none","summary":"Physically present attackers can bypass anti-downgrade protections to install vulnerable firmware and execute arbitrary code on Tesla Wall Connectors.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"wall_connector_firmware","vendor":"tesla"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-1328","name":"Security Version Number Mutable to Older Versions"}],"description":"Tesla Wall Connector Firmware Downgrade Vulnerability.
