SysTrack Agent, published on 28 May 2026. 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-2026-39929 in the wild and no public exploit code.\n\nAffected product: Lakeside Software, LLC. SysTrack Agent. 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-2026-39929/ (Markdown: https://insights.sbomify.com/CVE-2026-39929/index.md)","id":"CVE-2026-39929","markdown":"https://insights.sbomify.com/CVE-2026-39929/index.md","name":"CVE-2026-39929","record":{"aliases":["GHSA-96w5-xvg7-p24r"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SysTrack Agent","requires_auth":"none","summary":"Remote attackers can crash the Lakeside SysTrack Agent by sending a specially crafted UDP packet, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Lakeside SysTrack Agent versions prior to 11.2.1.28, 11.3.0.38, 11.4.0.24, 11.5.0.15 contain an out-of-bounds read vulnerability in the Command ID 30 UDP packet handler that allows remote attackers to crash the application by sending a specially crafted UDP packet.
