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-2026-87785 in the wild and no public exploit code.\n\nAffected product: Apache Syncope. 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-2026-87785/ (Markdown: https://insights.sbomify.com/CVE-2026-87785/index.md)","id":"CVE-2026-87785","markdown":"https://insights.sbomify.com/CVE-2026-87785/index.md","name":"CVE-2026-87785","record":{"aliases":["GHSA-v8g7-44pf-w6m4"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Syncope","requires_auth":"none","summary":"Attackers can spoof user privileges and bypass authentication if internal JWT settings are disclosed, requiring an upgrade to secure Apache Syncope.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","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-290","name":"Authentication Bypass by Spoofing"}],"description":"Authentication bypass by spoofing vulnerability in Apache Syncope.\n\nWhen the configured JWKS settings for internal JWT authentication are disclosed (at least protocol and key), an attacker can spoof another user's privileges after completing a successful authentication and obtaining a valid JWT.\n\nThis issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 through 4.0.7, from 4.1.0-M0 through 4.1.2.\n\nUsers are recommended to upgrade to version 4.0.8 / 4.1.3, which fix this issue.","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":"Apache Syncope: JWT subject spoofing","id":"CVE-2026-87785","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":"Dewa Kirim \u003c= 1.0.0 - Unauthenticated Stored XSS via Checkout Coordinates","id":"CVE-2026-87786"},"packages":[],"prev":{"headline":"Koinonia Link 1.1.2 - 1.1.4 - Subscriber+ Privilege Escalation to Administrator","id":"CVE-2026-87782"},"products":["Apache Syncope"],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["Apache Software Foundation"]},"summary":"Attackers can spoof user privileges and bypass authentication if internal JWT settings are disclosed, requiring an upgrade to secure Apache Syncope.","url":"https://insights.sbomify.com/CVE-2026-87785/"}
