An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-13308 in the wild and no public exploit code.\n\nAffected product: Autel MaxiCharger AC Elite Home. 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-2026-13308/ (Markdown: https://insights.sbomify.com/CVE-2026-13308/index.md)","id":"CVE-2026-13308","markdown":"https://insights.sbomify.com/CVE-2026-13308/index.md","name":"CVE-2026-13308","record":{"aliases":["GHSA-h225-8qf9-jw2x"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"EV charger","requires_auth":"none","summary":"Remote attackers can execute arbitrary code on Autel MaxiCharger AC Elite Home EV chargers via an integer underflow in WebSocket handling without authentication.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"}],"description":"Autel MaxiCharger AC Elite Home WebSockets Integer Underflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Elite Home EV chargers. Authentication is not required to exploit this vulnerability.\n\nThe specific flaw exists within the handling of WebSocket messages related to the OCPP service. The issue results from the lack of proper validation of user-supplied data, which can result in an integer underflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the device.
