It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2026-3502 in the wild since at least 2 Apr 2026.\n\nAffected product: TrueConf Client. 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-2026-3502/ (Markdown: https://insights.sbomify.com/CVE-2026-3502/index.md)","id":"CVE-2026-3502","markdown":"https://insights.sbomify.com/CVE-2026-3502/index.md","name":"CVE-2026-3502","record":{"aliases":["GHSA-33r5-g5m3-5m79"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"TrueConf Client","requires_auth":"high_privilege","summary":"Attackers can execute arbitrary code by substituting tampered update payloads due to missing integrity verification in TrueConf Client updates.","user_interaction":"required","vuln_class":"supply_chain"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"checkpoint","cpe":[{"product":"trueconf","vendor":"trueconf"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-494","name":"Download of Code Without Integrity Check"}],"description":"TrueConf Client downloads application update code and applies it without performing verification.
