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-2026-68821 in the wild and no public exploit code.\n\nAffected product: Microsoft App Installer. 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-2026-68821/ (Markdown: https://insights.sbomify.com/CVE-2026-68821/index.md)","id":"CVE-2026-68821","markdown":"https://insights.sbomify.com/CVE-2026-68821/index.md","name":"CVE-2026-68821","record":{"aliases":["GHSA-j4h5-8p8v-mfj6"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows Package Manager","requires_auth":"low_privilege","summary":"An authorized local attacker can exploit improper privilege management in Windows Package Manager to elevate privileges.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"app_installer","vendor":"microsoft"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Improper privilege management in Windows Package Manager allows an authorized attacker to elevate privileges locally.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Windows Package Manager Elevation of Privilege Vulnerability","id":"CVE-2026-68821","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":"Azure Confidential Ledger Remote Code Execution Vulnerability","id":"CVE-2026-68823"},"packages":[],"prev":{"headline":"Microsoft Windows Ancillary Function Driver for WinSock Use-After-Free","id":"CVE-2026-68820"},"products":["App Installer"],"published":"2026-08-11","related":[{"cvss_score":7.1,"headline":"Microsoft Windows AppX Installer Spoofing","id":"CVE-2021-43890","kev_date_added":"2021-12-15","published":"2021-12-15"},{"cvss_score":7.8,"headline":"Windows App Installer Spoofing Vulnerability","id":"CVE-2024-38177","kev_date_added":null,"published":"2024-08-13"}],"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":"2026-10-28","vendors":["Microsoft"]},"summary":"An authorized local attacker can exploit improper privilege management in Windows Package Manager to elevate privileges.","url":"https://insights.sbomify.com/CVE-2026-68821/"}
