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-2026-33784 in the wild and no public exploit code.\n\nAffected product: Juniper Networks JSI LWC. 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-2026-33784/ (Markdown: https://insights.sbomify.com/CVE-2026-33784/index.md)","id":"CVE-2026-33784","markdown":"https://insights.sbomify.com/CVE-2026-33784/index.md","name":"CVE-2026-33784","record":{"aliases":["GHSA-g6hm-r7f2-4j2f"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Juniper JSI vLWC","requires_auth":"none","summary":"An unauthenticated attacker can gain full control of Juniper JSI Virtual Lightweight Collector devices using the default high-privileged password.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"virtual_lightweight_collector","vendor":"juniper"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:L/AU:Y/R:U/RE:L","version":"4.0"},"cwes":[{"id":"CWE-1393","name":"Use of Default Password"}],"description":"A Use of Default Password vulnerability in the Juniper Networks \n\nSupport Insights (JSI) \n\nVirtual Lightweight Collector (vLWC) allows an unauthenticated, network-based attacker to take full control of the device.\n\nvLWC software images ship with an initial password for a high privileged account.
