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-2026-40139 in the wild and no public exploit code.\n\nAffected product: BeyondTrust Privileged Remote Access. 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-2026-40139/ (Markdown: https://insights.sbomify.com/CVE-2026-40139/index.md)","id":"CVE-2026-40139","markdown":"https://insights.sbomify.com/CVE-2026-40139/index.md","name":"CVE-2026-40139","record":{"aliases":["GHSA-5wv8-v74x-qrjc"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Remote Support Appliance","requires_auth":"none","summary":"Unauthenticated attackers can bypass access controls to gain unauthorized access to the appliance, including elevated privileges, if specific authentication settings are enabled.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"BT","cpe":[{"product":"privileged_remote_access","vendor":"beyondtrust"},{"product":"remote_support","vendor":"beyondtrust"}],"cvss":{"score":9.2,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"A critical pre-authentication vulnerability exists in the authentication subsystem of BeyondTrust Remote Support. Improper processing of authentication requests may allow an unauthenticated remote attacker to bypass access controls and gain unauthorized access to the appliance, including accounts with elevated privileges.
