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-2026-57028 in the wild and no public exploit code.\n\nAffected product: Juniper Junos Os Evolved. 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-2026-57028/ (Markdown: https://insights.sbomify.com/CVE-2026-57028/index.md)","id":"CVE-2026-57028","markdown":"https://insights.sbomify.com/CVE-2026-57028/index.md","name":"CVE-2026-57028","record":{"aliases":["GHSA-jvwv-xxr5-8965"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Junos OS Evolved","requires_auth":"none","summary":"An unauthenticated attacker can access internal license management via an exposed port, causing license exhaustion and denial of service.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"juniper","cpe":[{"product":"junos_os_evolved","vendor":"juniper"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/AU:Y/R:U/RE:M","version":"4.0"},"cwes":[{"id":"CWE-923","name":"Improper Restriction of Communication Channel to Intended Endpoints"}],"description":"An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause license exhaustion.\n\nDue to an incorrect initialization, a process which should only be able to communicate internally within the device, can be reached over the network via an open port.
