It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-31846 in the wild and no public exploit code.\n\nAffected product: Nexxt Solutions Nebula 300+ / Tenda F3 V2.0 Firmware. 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-2026-31846/ (Markdown: https://insights.sbomify.com/CVE-2026-31846/index.md)","id":"CVE-2026-31846","markdown":"https://insights.sbomify.com/CVE-2026-31846/index.md","name":"CVE-2026-31846","record":{"aliases":["GHSA-gf7h-gjp8-r79h"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nexxt Nebula 300+","requires_auth":"none","summary":"An unauthenticated attacker can retrieve administrator credentials from the device, leading to full administrative access.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TuranSec","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Missing authentication in the /goform/ate endpoint in Nexxt Solutions Nebula 300+ firmware through version 12.01.01.37 allows an adjacent unauthenticated attacker to retrieve sensitive device information, including the administrator password.
