Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-13666 in the wild and no public exploit code.\n\nAffected product: Synology DiskStation Manager (DSM). 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-2026-13666/ (Markdown: https://insights.sbomify.com/CVE-2026-13666/index.md)","id":"CVE-2026-13666","markdown":"https://insights.sbomify.com/CVE-2026-13666/index.md","name":"CVE-2026-13666","record":{"aliases":["GHSA-7969-99rg-6xxh"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"NAS operating system","requires_auth":"low_privilege","summary":"Remote authenticated users can write limited files via CRLF injection in the Sharing API when a victim clicks a sharing URL.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"}],"description":"An improper neutralization of CRLF sequences ('CRLF Injection') vulnerability in Sharing API in Synology DiskStation Manager (DSM) before 7.2.1-69057-12, 7.2.2-72806-9, 7.3.2-86009-4 and 7.4-90075 allows remote authenticated users to write limited files when a victim clicks a sharing URL.","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":"Other in DiskStation Manager (DSM)","id":"CVE-2026-13666","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Missing authorization in DiskStation Manager (DSM)","id":"CVE-2026-13673"},"packages":[],"prev":{"headline":"Weak cryptography in DiskStation Manager (DSM)","id":"CVE-2026-13639"},"products":["DiskStation Manager (DSM)"],"published":"2026-09-18","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":"2026-09-18","vendors":["Synology"]},"summary":"Remote authenticated users can write limited files via CRLF injection in the Sharing API when a victim clicks a sharing URL.","url":"https://insights.sbomify.com/CVE-2026-13666/"}
