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-2026-47831 in the wild and no public exploit code.\n\nAffected product: Cloud Foundry Foundation bosh-windows-stemcell-builder. 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-2026-47831/ (Markdown: https://insights.sbomify.com/CVE-2026-47831/index.md)","id":"CVE-2026-47831","markdown":"https://insights.sbomify.com/CVE-2026-47831/index.md","name":"CVE-2026-47831","record":{"aliases":["GHSA-4qp9-f9vm-49xq"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Bosh Windows Stemcell Builder","requires_auth":"none","summary":"Weak random number generation in password creation allows remote attackers to brute-force SSH logins, compromising system access.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[],"description":"Use of a cryptographically weak random number generator in the GenerateRandomPassword function in bosh-windows-stemcell-builder allows a remote attacker to brute-force the resulting SSH login via TCP/22.\nAffected versions: bosh-windows-stemcell-builder versions prior to v2019.98.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cryptographically Weak Password Generation in bosh-windows-stemcell-builder Allows Remote SSH Brute-Force Attacks","id":"CVE-2026-47831","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in bpm-release","id":"CVE-2026-47833"},"packages":[],"prev":{"headline":"Incorrect Permission Assignment Allows Local Privilege Escalation to SYSTEM via Executable Overwrite","id":"CVE-2026-47830"},"products":["bosh-windows-stemcell-builder"],"published":"2026-07-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-09","vendors":["Cloud Foundry Foundation"]},"summary":"Weak random number generation in password creation allows remote attackers to brute-force SSH logins, compromising system access.","url":"https://insights.sbomify.com/CVE-2026-47831/"}
