Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-13489 exists.\n\nAffected product: 78 xiaozhi-esp32. 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-2026-13489/ (Markdown: https://insights.sbomify.com/CVE-2026-13489/index.md)","id":"CVE-2026-13489","markdown":"https://insights.sbomify.com/CVE-2026-13489/index.md","name":"CVE-2026-13489","record":{"aliases":["GHSA-2vm4-w283-mr2p"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"ESP32 firmware","requires_auth":"low_privilege","summary":"Improper synchronization in the MCP Response Handler allows remote attackers to exploit race conditions, potentially causing undefined behavior or denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-662","name":"Improper Synchronization"}],"description":"A weakness has been identified in 78 xiaozhi-esp32 up to 2.2.6.
