It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-76159 in the wild and no public exploit code.\n\nAffected product: Duplicati. 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-2026-76159/ (Markdown: https://insights.sbomify.com/CVE-2026-76159/index.md)","id":"CVE-2026-76159","markdown":"https://insights.sbomify.com/CVE-2026-76159/index.md","name":"CVE-2026-76159","record":{"aliases":["GHSA-8x3r-pmm8-3j9w"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows backup software","requires_auth":"low_privilege","summary":"A local low-privileged attacker can escalate privileges to SYSTEM by exploiting incorrect permissions in the configuration loader of Duplicati for Windows.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ZUSO ART","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"Incorrect Permission Assignment for Critical Resource in the  configuration loader of Duplicati for Windows versions before v2.4.0.0 allows a local low-privileged attacker to escalate       privileges to NT AUTHORITY\\SYSTEM via an attacker-controlled preload.json file.","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":"Duplicati for Windows - Incorrect Permission Assignment for Critical Resource","id":"CVE-2026-76159","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.","id":"CVE-2026-76160"},"packages":[],"prev":{"headline":"Datiphy Data Management Center - External Control of File Name or Path","id":"CVE-2026-76158"},"products":["Duplicati"],"published":"2026-09-15","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":"2026-09-15","vendors":["Duplicati"]},"summary":"A local low-privileged attacker can escalate privileges to SYSTEM by exploiting incorrect permissions in the configuration loader of Duplicati for Windows.","url":"https://insights.sbomify.com/CVE-2026-76159/"}
