Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-19273 in the wild and no public exploit code.\n\nAffected product: IBM Sterling B2B Integrator. 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-2026-19273/ (Markdown: https://insights.sbomify.com/CVE-2026-19273/index.md)","id":"CVE-2026-19273","markdown":"https://insights.sbomify.com/CVE-2026-19273/index.md","name":"CVE-2026-19273","record":{"aliases":["GHSA-8f75-86xx-87vh"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Sterling B2B Integrator","requires_auth":"low_privilege","summary":"Remote authenticated attackers can bypass security restrictions in the Dashboard of IBM Sterling B2B Integrator and File Gateway due to improper authentication.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"IBM Sterling B2B Integrator 6.2.0.0 through 6.2.0.6_2, 6.2.1.0 - 6.2.1.2, 6.2.2.0 - 6.2.2.1 and IBM Sterling File Gateway 6.2.0.0 through 6.2.0.6_2, 6.2.1.0 - 6.2.1.2, 6.2.2.0 - 6.2.2.1 Standard Edition could allow a remote authenticated attacker to bypass security restrictions due to improper authentication.","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":"The Dashboard of IBM Sterling B2B Integrator and IBM Sterling File Gateway are Vulnerable to Improper Access Control","id":"CVE-2026-19273","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"IBM Instana Observability is affected by multiple vulnerabilities within Instana Agent container image","id":"CVE-2026-19274"},"packages":[],"prev":{"headline":"Blind LDAP Injection in Sign-In Endpoint in TÜBİTAK BİLGEM's Liderahenk","id":"CVE-2026-19271"},"products":["Sterling B2B Integrator","Sterling File Gateway"],"published":"2026-09-14","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":"2026-09-15","vendors":["IBM"]},"summary":"Remote authenticated attackers can bypass security restrictions in the Dashboard of IBM Sterling B2B Integrator and File Gateway due to improper authentication.","url":"https://insights.sbomify.com/CVE-2026-19273/"}
