Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-28286 in the wild and no public exploit code.\n\nAffected product: IceWhaleTech ZimaOS. 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-2026-28286/ (Markdown: https://insights.sbomify.com/CVE-2026-28286/index.md)","id":"CVE-2026-28286","markdown":"https://insights.sbomify.com/CVE-2026-28286/index.md","name":"CVE-2026-28286","record":{"aliases":["GHSA-65mg-9gw5-vr7g"],"analysis":{"component_type":"operating_system","fix_type":"no_fix_stated","impacts":["data_modify","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"ZimaOS","requires_auth":"low_privilege","summary":"Attackers can bypass frontend restrictions to create files in sensitive system directories via the API, potentially leading to privilege escalation.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"zimaos","vendor":"zimaspace"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.5.2-beta3, the application enforces restrictions in the frontend/UI to prevent users from creating files or folders in internal OS paths. However, when interacting directly with the API, the restrictions are bypass-able. By sending a crafted request targeting paths like /etc, /usr, or other sensitive system directories, the API successfully creates files or directories in locations where normal users should have no write access. This indicates that the API does not properly validate the target path, allowing unauthorized operations on critical system directories. No known patch is publicly available.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-04-05","github_poc":1,"max_poc_stars":3,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-04-05T18:01:16Z","kind":"github_poc","ref":"https://github.com/Rushi9/zimaos-cve-2026-28286-arbitrary-file-write","stars":3,"title":"ZimaOS CVE-2026-28286 arbitrary file write PoC \u0026 verification toolkit"}],"tier":"poc_unverified"},"has_fix":false,"headline":"ZimaOS: Unauthorized Creation of Files/Folders in Restricted System Directories via API","id":"CVE-2026-28286","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"FreePBX: Authenticated Remote Code Execution via Recordings Module AJAX Endpoints","id":"CVE-2026-28287"},"packages":[],"prev":{"headline":"FreePBX: Authenticated SQL Injection Vulnerabilities in FreePBX Logfiles Module","id":"CVE-2026-28284"},"products":["ZimaOS"],"published":"2026-03-02","related":[{"cvss_score":9.4,"headline":"ZimaOS has Authentication Bypass via System-Level Username","id":"CVE-2026-21891","kev_date_added":null,"published":"2026-01-08"},{"cvss_score":9.1,"headline":"Arbitrary internal service access via /v1/sys/proxy when Cloudflare Tunnel is enabled on ZimaOS","id":"CVE-2026-28798","kev_date_added":null,"published":"2026-04-03"},{"cvss_score":8.6,"headline":"ZimaOS: Arbitrary Deletion of Internal System Files via API Path Manipulation","id":"CVE-2026-28442","kev_date_added":null,"published":"2026-03-05"},{"cvss_score":7.5,"headline":"ZimaOS Arbitrary File Read via Parameter Manipulation","id":"CVE-2024-48931","kev_date_added":null,"published":"2024-10-24"},{"cvss_score":7.5,"headline":"ZimaOS (Installed Applications and System Information) has Unauthorized Sensitive Data Leak","id":"CVE-2024-49357","kev_date_added":null,"published":"2024-10-24"},{"cvss_score":7.5,"headline":"ZimaOS vulnerable to Directory Listing via Parameter Manipulation","id":"CVE-2024-49359","kev_date_added":null,"published":"2024-10-24"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-03","vendors":["IceWhaleTech"]},"summary":"Attackers can bypass frontend restrictions to create files in sensitive system directories via the API, potentially leading to privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-28286/"}
