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-2026-9789 in the wild and no public exploit code.\n\nAffected product: Acer NitrorSense V3. 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-2026-9789/ (Markdown: https://insights.sbomify.com/CVE-2026-9789/index.md)","id":"CVE-2026-9789","markdown":"https://insights.sbomify.com/CVE-2026-9789/index.md","name":"CVE-2026-9789","record":{"aliases":["GHSA-pcjv-vg43-2hf7"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Acer NitroSense software","requires_auth":"low_privilege","summary":"A local attacker can escalate privileges to system authority by exploiting weak ACLs on a named pipe to delete arbitrary files.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Acer","cpe":[],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"},{"id":"CWE-284","name":"Improper Access Control"},{"id":"CWE-269","name":"Improper Privilege Management"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A Local Privilege Escalation (LPE) vulnerability affects Acer NitroSense software versions prior to 3.01.3052.
