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-2020-26557 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-26557/ (Markdown: https://insights.sbomify.com/CVE-2020-26557/index.md)","id":"CVE-2020-26557","markdown":"https://insights.sbomify.com/CVE-2020-26557/index.md","name":"CVE-2020-26557","record":{"aliases":["GHSA-gprg-wq36-vj82","ROOT-OS-UBUNTU-2204-CVE-2020-26557","UBUNTU-CVE-2020-26557"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Bluetooth Mesh stack","requires_auth":"none","summary":"A nearby attacker can brute-force the Bluetooth Mesh provisioning AuthValue to bypass authentication and join the network.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mesh_profile","vendor":"bluetooth"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"Mesh Provisioning in the Bluetooth Mesh profile 1.0 and 1.0.1 may permit a nearby device (without possession of the AuthValue used in the provisioning protocol) to determine the AuthValue via a brute-force attack (unless the AuthValue is sufficiently random and changed each time).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Auth bypass in n/a","id":"CVE-2020-26557","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2020-26558"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2020-26556"},"products":["n/a"],"published":"2021-05-24","related":[{"cvss_score":8.8,"headline":"Auth bypass in n/a","id":"CVE-2020-26559","kev_date_added":null,"published":"2021-05-24"},{"cvss_score":8.1,"headline":"Auth bypass in n/a","id":"CVE-2020-26560","kev_date_added":null,"published":"2021-05-24"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2025-11-04","vendors":["n/a"]},"summary":"A nearby attacker can brute-force the Bluetooth Mesh provisioning AuthValue to bypass authentication and join the network.","url":"https://insights.sbomify.com/CVE-2020-26557/"}
