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-2026-18806 in the wild and no public exploit code.\n\nAffected product: TÜBİTAK BİLGEM Software Technologies Research Institute pardus-image-writer. 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-2026-18806/ (Markdown: https://insights.sbomify.com/CVE-2026-18806/index.md)","id":"CVE-2026-18806","markdown":"https://insights.sbomify.com/CVE-2026-18806/index.md","name":"CVE-2026-18806","record":{"aliases":["GHSA-55j4-vcvp-5mxf"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Pardus image writer","requires_auth":"low_privilege","summary":"Attackers can write to arbitrary block devices due to missing validation, potentially causing data loss or system denial of service.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TR-CERT","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"External control of file name or path vulnerability in TÜBİTAK BİLGEM Software Technologies Research Institute pardus-image-writer allows Removing Important Client Functionality.\n\nThis issue affects pardus-image-writer: before 0.9.0.","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":"Arbitrary Block Device Write via Missing Validation in TÜBİTAK BİLGEM's pardus-image-writer","id":"CVE-2026-18806","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":"ECS \u003c 4.3.13 - Contributor+ Arbitrary Post Binding and Global Preset Modification via Dynamic Repeater Handlers","id":"CVE-2026-18807"},"packages":[],"prev":{"headline":"Stored Clickhouse SQL Injection Through Customer Usage Attribution","id":"CVE-2026-18801"},"products":["pardus-image-writer"],"published":"2026-08-04","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":"partial"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["TÜBİTAK BİLGEM Software Technologies Research Institute"]},"summary":"Attackers can write to arbitrary block devices due to missing validation, potentially causing data loss or system denial of service.","url":"https://insights.sbomify.com/CVE-2026-18806/"}
