Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4064 in the wild and no public exploit code.\n\nAffected product: Devolutions PowerShell Universal. 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-2026-4064/ (Markdown: https://insights.sbomify.com/CVE-2026-4064/index.md)","id":"CVE-2026-4064","markdown":"https://insights.sbomify.com/CVE-2026-4064/index.md","name":"CVE-2026-4064","record":{"aliases":["GHSA-979h-vff8-97jm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PowerShell Universal","requires_auth":"low_privilege","summary":"Authenticated users can bypass role-based access controls to perform privileged operations, read sensitive data, and disrupt services in PowerShell Universal.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"DEVOLUTIONS","cpe":[{"product":"powershell_universal","vendor":"ironmansoftware"}],"cvss":{"score":8.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Missing authorization checks on multiple gRPC service endpoints in PowerShell Universal before 2026.1.4 allows an authenticated user with any valid token to bypass role-based access controls and perform privileged operations — including reading sensitive data, creating or deleting resources, and disrupting service operations — via crafted gRPC requests.","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":"Missing authorization in PowerShell Universal","id":"CVE-2026-4064","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in Smart Slider 3","id":"CVE-2026-4065"},"packages":[],"prev":{"headline":"Missing authorization in Social Icons Widget \u0026 Block – Social Media Icons \u0026 Share Buttons","id":"CVE-2026-4063"},"products":["PowerShell Universal"],"published":"2026-03-17","related":[{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2023-49213","kev_date_added":null,"published":"2023-11-23"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2022-45183","kev_date_added":null,"published":"2022-11-14"},{"cvss_score":7.2,"headline":"Path traversal in n/a","id":"CVE-2022-45184","kev_date_added":null,"published":"2022-11-14"},{"cvss_score":6.1,"headline":"Cross-site scripting in PowerShell Universal","id":"CVE-2026-0618","kev_date_added":null,"published":"2026-01-07"},{"cvss_score":5.5,"headline":"Denial of service in PowerShell Universal","id":"CVE-2026-3563","kev_date_added":null,"published":"2026-03-17"},{"cvss_score":5.5,"headline":"Hardcoded credentials in PowerShell Universal","id":"CVE-2026-3277","kev_date_added":null,"published":"2026-02-27"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-17","vendors":["Devolutions"]},"summary":"Authenticated users can bypass role-based access controls to perform privileged operations, read sensitive data, and disrupt services in PowerShell Universal.","url":"https://insights.sbomify.com/CVE-2026-4064/"}
