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-2026-21672 in the wild and no public exploit code.\n\nAffected product: Veeam Backup and Replication. 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-2026-21672/ (Markdown: https://insights.sbomify.com/CVE-2026-21672/index.md)","id":"CVE-2026-21672","markdown":"https://insights.sbomify.com/CVE-2026-21672/index.md","name":"CVE-2026-21672","record":{"aliases":["GHSA-h68h-qcxp-qv6v"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Veeam Backup \u0026 Replication","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges on Windows-based Veeam Backup \u0026 Replication servers, requiring immediate patching by administrators.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-538","name":"Insertion of Sensitive Information into Externally-Accessible File or Directory"}],"description":"A vulnerability allowing local privilege escalation on Windows-based Veeam Backup \u0026 Replication servers.","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":"Privilege escalation in Backup and Replication","id":"CVE-2026-21672","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"iccDEV has Integer Overflow/Underflow in CIccXmlArrayType::ParseTextCountNum()","id":"CVE-2026-21673"},"packages":[],"prev":{"headline":"Code injection in Software Appliance","id":"CVE-2026-21671"},"products":["Backup and Replication"],"published":"2026-03-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-05-10","vendors":["Veeam"]},"summary":"Local attackers can escalate privileges on Windows-based Veeam Backup \u0026 Replication servers, requiring immediate patching by administrators.","url":"https://insights.sbomify.com/CVE-2026-21672/"}
