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-2025-27909 in the wild and no public exploit code.\n\nAffected product: Ibm Concert. 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-2025-27909/ (Markdown: https://insights.sbomify.com/CVE-2025-27909/index.md)","id":"CVE-2025-27909","markdown":"https://insights.sbomify.com/CVE-2025-27909/index.md","name":"CVE-2025-27909","record":{"aliases":["GHSA-22cj-gf6g-gpgc"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Concert Software","requires_auth":"none","summary":"An attacker can perform privileged actions due to overly permissive CORS settings in IBM Concert Software.","user_interaction":"required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"concert","vendor":"ibm"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-697","name":"Incorrect Comparison"},{"id":"CWE-942","name":"Permissive Cross-domain Security Policy with Untrusted Domains"}],"description":"IBM Concert Software 1.0.0 through 1.1.0 uses cross-origin resource sharing (CORS) which could allow an attacker to carry out privileged actions as the domain name is not being limited to only trusted domains.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"IBM Concert Software cross-origin resource sharing","id":"CVE-2025-27909","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ibm:concert","products":["ibm:concert"],"type":"misconfiguration","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2025-27910"},"packages":[],"prev":{"headline":"IBM WebSphere Application Server server-side request forgery","id":"CVE-2025-27907"},"products":["Concert Software"],"published":"2025-08-18","related":[{"cvss_score":9.8,"headline":"Multiple Vulnerabilities in IBM Concert Software","id":"CVE-2026-6721","kev_date_added":null,"published":"2026-09-23"},{"cvss_score":9.8,"headline":"Multiple Vulnerabilities in IBM Concert Software","id":"CVE-2026-6730","kev_date_added":null,"published":"2026-09-23"},{"cvss_score":9.8,"headline":"Multiple Vulnerabilities in IBM Concert Software","id":"CVE-2026-6928","kev_date_added":null,"published":"2026-09-23"},{"cvss_score":9.1,"headline":"Multiple Vulnerabilities in IBM Concert Software","id":"CVE-2026-3627","kev_date_added":null,"published":"2026-08-28"},{"cvss_score":8.8,"headline":"Multiple Vulnerabilities in IBM Concert Software","id":"CVE-2025-33015","kev_date_added":null,"published":"2026-01-20"},{"cvss_score":7.8,"headline":"Multiple Vulnerabilities in IBM Concert Software","id":"CVE-2026-6794","kev_date_added":null,"published":"2026-09-23"},{"cvss_score":7.8,"headline":"Multiple Vulnerabilities in IBM Concert Software","id":"CVE-2026-6935","kev_date_added":null,"published":"2026-09-23"}],"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":"2025-08-18","vendors":["IBM"]},"summary":"An attacker can perform privileged actions due to overly permissive CORS settings in IBM Concert Software.","url":"https://insights.sbomify.com/CVE-2025-27909/"}
