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-2026-75878 in the wild and no public exploit code.\n\nAffected product: IBM Sterling File Gateway. 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-2026-75878/ (Markdown: https://insights.sbomify.com/CVE-2026-75878/index.md)","id":"CVE-2026-75878","markdown":"https://insights.sbomify.com/CVE-2026-75878/index.md","name":"CVE-2026-75878","record":{"aliases":["GHSA-652p-cfff-8crm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM Sterling File Gateway","requires_auth":"none","summary":"Remote attackers can bypass authentication via an unvalidated SSO header to gain full access to IBM Sterling File Gateway sessions.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"IBM Sterling File Gateway could allow a remote attacker to bypass authentication and obtain a fully authenticated session due to improper authentication via an unvalidated SSO header.","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 Sterling File Gateway is Vulnerable to Authentication Bypass","id":"CVE-2026-75878","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":"Apache Artemis, Apache ActiveMQ Artemis: Message selector wildcard handling could lead to denial of service","id":"CVE-2026-75880"},"packages":[],"prev":{"headline":"TRENDnet TV-IP751WIC alphapd FUN_0043372C stack-based overflow","id":"CVE-2026-75877"},"products":["Sterling File Gateway"],"published":"2026-09-18","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-19","vendors":["IBM"]},"summary":"Remote attackers can bypass authentication via an unvalidated SSO header to gain full access to IBM Sterling File Gateway sessions.","url":"https://insights.sbomify.com/CVE-2026-75878/"}
