An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-84484 exists.\n\nAffected product: nasa-jpl ION-DTN. 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-2026-84484/ (Markdown: https://insights.sbomify.com/CVE-2026-84484/index.md)","id":"CVE-2026-84484","markdown":"https://insights.sbomify.com/CVE-2026-84484/index.md","name":"CVE-2026-84484","record":{"aliases":["GHSA-5vmj-4h65-2fh8","GHSA-85pw-28vw-2jf7"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"DTN protocol stack","requires_auth":"none","summary":"Unauthenticated remote attackers can read memory via truncated SDNV values in ION-DTN, potentially exposing sensitive data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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-125","name":"Out-of-bounds Read"}],"description":"ION-DTN versions before 4.2.0 contain an out-of-bounds read vulnerability in the decodeSdnv function that allows unauthenticated remote attackers to read memory by sending truncated SDNV values.
