An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-3303 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-2026-3303/ (Markdown: https://insights.sbomify.com/CVE-2026-3303/index.md)","id":"CVE-2026-3303","markdown":"https://insights.sbomify.com/CVE-2026-3303/index.md","name":"CVE-2026-3303","record":{"aliases":["GHSA-m52p-rqhq-p69f"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Concert software","requires_auth":"none","summary":"An attacker can perform privileged actions or access data due to overly permissive CORS settings in IBM Concert.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-942","name":"Permissive Cross-domain Security Policy with Untrusted Domains"}],"description":"IBM Concert 1.0 through 3.0.0 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":null,"headline":"IBM Concert Software Permissive Cross-domain Security Policy","id":"CVE-2026-3303","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"misconfiguration","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Multer vulnerable to Denial of Service via incomplete cleanup","id":"CVE-2026-3304"},"packages":[],"prev":{"headline":"SourceCodester Doctor Appointment System Sign Up register.php cross site scripting","id":"CVE-2026-3302"},"products":["Concert"],"published":"2026-10-19","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":"2026-10-20","vendors":["IBM"]},"summary":"An attacker can perform privileged actions or access data due to overly permissive CORS settings in IBM Concert.","url":"https://insights.sbomify.com/CVE-2026-3303/"}
