It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2025-66592 and fix it if it is affected.\n\nWhat it is: CVE-2025-66592 is a medium-severity path traversal vulnerability in Synology Active Backup for Business Agent, published on 27 May 2026. 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-2025-66592 in the wild and no public exploit code.\n\nAffected product: Synology Active Backup for Business Agent. 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-2025-66592/ (Markdown: https://insights.sbomify.com/CVE-2025-66592/index.md)","id":"CVE-2025-66592","markdown":"https://insights.sbomify.com/CVE-2025-66592/index.md","name":"CVE-2025-66592","record":{"aliases":["GHSA-v5xx-f9gc-j856"],"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":"Synology backup agent","requires_auth":"none","summary":"Local attackers can write arbitrary files and cause denial of service during installation due to origin validation errors in the Synology backup agent.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"active_backup_for_business_agent","vendor":"synology"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"An origin validation error vulnerability in Synology Active Backup for Business Agent before 3.1.0-4967 allows local users to write arbitrary files with restricted content and conduct denial-of-service during installation.","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":"Path traversal in Synology Active Backup for Business Agent","id":"CVE-2025-66592","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Synology Assistant","id":"CVE-2025-66593"},"packages":[],"prev":{"headline":"Out-of-bounds Write vulnerability in AzeoTech DAQFactory","id":"CVE-2025-66590"},"products":["Synology Active Backup for Business Agent"],"published":"2026-05-27","related":[{"cvss_score":6.5,"headline":"Path traversal in Active Backup for Business","id":"CVE-2024-47265","kev_date_added":null,"published":"2025-02-13"},{"cvss_score":5.5,"headline":"Missing authorization in Synology Active Backup for Business Agent","id":"CVE-2023-52949","kev_date_added":null,"published":"2024-09-26"},{"cvss_score":5.3,"headline":"Information disclosure in Synology Active Backup for Business Agent","id":"CVE-2023-52950","kev_date_added":null,"published":"2024-09-26"},{"cvss_score":5,"headline":"Information disclosure in Synology Active Backup for Business Agent","id":"CVE-2023-52948","kev_date_added":null,"published":"2024-09-26"},{"cvss_score":4.9,"headline":"Path traversal in Active Backup for Business","id":"CVE-2024-47264","kev_date_added":null,"published":"2025-02-13"},{"cvss_score":4,"headline":"Missing authorization in Synology Active Backup for Business Agent","id":"CVE-2023-52947","kev_date_added":null,"published":"2024-09-26"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-06-02","vendors":["Synology"]},"summary":"Local attackers can write arbitrary files and cause denial of service during installation due to origin validation errors in the Synology backup agent.","url":"https://insights.sbomify.com/CVE-2025-66592/"}
