Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-15556 in the wild and no public exploit code.\n\nAffected product: Red Hat JBoss Enterprise Application Platform 7. 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-2026-15556/ (Markdown: https://insights.sbomify.com/CVE-2026-15556/index.md)","id":"CVE-2026-15556","markdown":"https://insights.sbomify.com/CVE-2026-15556/index.md","name":"CVE-2026-15556","record":{"aliases":["GHSA-vw9v-mpfh-qwg3"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"JBoss EAP","requires_auth":"low_privilege","summary":"Attackers can forge SAML responses to bypass authentication and gain unauthorized access with any role in JBoss EAP applications.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"A flaw was found in Picketlink's SP signature validation; a SAML response containing zero assertion elements matching the signature check can allow an attacker to forge a SAML response and auth as any principal with any roles on the protected application.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Picketlink-federation: picketlink saml 2.0 auth bypass via missing assertions","id":"CVE-2026-15556","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":6,"next":{"headline":"waooAI waoowaoo Internal Task Header api-auth.ts requireProjectAuthLight improper authentication","id":"CVE-2026-15557"},"packages":[],"prev":{"headline":"Deserialization in Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7","id":"CVE-2026-15555"},"products":["Red Hat JBoss Enterprise Application Platform 7","Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7","Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 8","Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 9","Red Hat JBoss Enterprise Application Platform 7.4.25","Red Hat JBoss Enterprise Application Platform 8","Red Hat JBoss Enterprise Application Platform Expansion Pack"],"published":"2026-08-11","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":"total"},"state":"PUBLISHED","updated":"2026-10-26","vendors":["Red Hat"]},"summary":"Attackers can forge SAML responses to bypass authentication and gain unauthorized access with any role in JBoss EAP applications.","url":"https://insights.sbomify.com/CVE-2026-15556/"}
