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-2026-40530 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-2026-40530/ (Markdown: https://insights.sbomify.com/CVE-2026-40530/index.md)","id":"CVE-2026-40530","markdown":"https://insights.sbomify.com/CVE-2026-40530/index.md","name":"CVE-2026-40530","record":{"aliases":["GHSA-j93c-qcgp-gv6m"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology NAS OS","requires_auth":"low_privilege","summary":"Authenticated attackers can exploit CRLF injection in the User API to read or write arbitrary files and cause denial of service.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"}],"description":"An improper neutralization of CRLF sequences ('CRLF injection') vulnerability in User API in Synology DiskStation Manager (DSM) before 7.2.1-69057-10, 7.2.2-72806-7 and 7.3.2-86009-2 allows remote authenticated users to read or write arbitrary files and conduct denial-of-service attacks after the system is rebooted.","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-2026-40530","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Integer overflow in DiskStation Manager (DSM)","id":"CVE-2026-40531"},"packages":[],"prev":{"headline":"SQL injection in CMS ALAYA","id":"CVE-2026-40529"},"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":"total"},"state":"PUBLISHED","updated":"2026-09-18","vendors":["Synology"]},"summary":"Authenticated attackers can exploit CRLF injection in the User API to read or write arbitrary files and cause denial of service.","url":"https://insights.sbomify.com/CVE-2026-40530/"}
