An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-109390 exists.\n\nAffected product: AnyDesk. 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-2026-109390/ (Markdown: https://insights.sbomify.com/CVE-2026-109390/index.md)","id":"CVE-2026-109390","markdown":"https://insights.sbomify.com/CVE-2026-109390/index.md","name":"CVE-2026-109390","record":{"aliases":["GHSA-p2jv-fpmf-jqjw"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Remote desktop software","requires_auth":"none","summary":"Unauthenticated remote attackers can execute arbitrary code as root via a heap-based buffer overflow in AnyDesk without user approval.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-130","name":"Improper Handling of Length Parameter Inconsistency"}],"description":"AnyDesk before 8.0.3 allows unauthenticated remote attackers to execute arbitrary code via a heap-based buffer overflow, as demonstrated on Linux for command execution as root without the victim approving desktop control.
