An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-15966 in the wild and no public exploit code.\n\nAffected product: Progress MOVEit Transfer. 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-2026-15966/ (Markdown: https://insights.sbomify.com/CVE-2026-15966/index.md)","id":"CVE-2026-15966","markdown":"https://insights.sbomify.com/CVE-2026-15966/index.md","name":"CVE-2026-15966","record":{"aliases":["GHSA-9rcg-65vx-h53x"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Managed File Transfer","requires_auth":"none","summary":"Attackers can bypass cross-domain restrictions to access sensitive data or perform unauthorized actions due to permissive CORS settings.","user_interaction":"required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ProgressSoftware","cpe":[{"product":"moveit_transfer","vendor":"progress"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-942","name":"Permissive Cross-domain Security Policy with Untrusted Domains"}],"description":"Permissive cross-domain security policy with untrusted domains vulnerability in Progress MOVEit Transfer.\n\nThis issue affects MOVEit Transfer: before 2025.1.5, from 2026.0.0 before 2026.0.3.","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":"Improper CORS handling in MOVEit Transfer","id":"CVE-2026-15966","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"misconfiguration","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"MOVEit Transfer refresh-token processing does not enforce updated account restrictions","id":"CVE-2026-15967"},"packages":[],"prev":{"headline":"MaxUpload \u003c= 1.4.0 - Unauthenticated Arbitrary File Upload via 'resumableFilename' Parameter","id":"CVE-2026-15965"},"products":["MOVEit Transfer"],"published":"2026-07-23","related":[{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2023-35708","kev_date_added":null,"published":"2023-06-16"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2021-38159","kev_date_added":null,"published":"2021-08-07"},{"cvss_score":9.1,"headline":"MOVEit Transfer Authentication Bypass Vulnerability","id":"CVE-2024-5806","kev_date_added":null,"published":"2024-06-25"},{"cvss_score":9.1,"headline":"SQL injection in n/a","id":"CVE-2023-36934","kev_date_added":null,"published":"2023-07-05"},{"cvss_score":9.1,"headline":"SQL injection in n/a","id":"CVE-2023-35036","kev_date_added":null,"published":"2023-06-12"},{"cvss_score":8.8,"headline":"MOVEit Transfer Service Directory Writable by Local Users Enables Local Privilege Escalation","id":"CVE-2026-87093","kev_date_added":null,"published":"2026-10-14"},{"cvss_score":8.8,"headline":"MOVEit Transfer Secure Messaging Authentication Bypass","id":"CVE-2026-89067","kev_date_added":null,"published":"2026-10-14"}],"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":"total"},"state":"PUBLISHED","updated":"2026-07-25","vendors":["Progress"]},"summary":"Attackers can bypass cross-domain restrictions to access sensitive data or perform unauthorized actions due to permissive CORS settings.","url":"https://insights.sbomify.com/CVE-2026-15966/"}
