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-2026-87802 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-2026-87802/ (Markdown: https://insights.sbomify.com/CVE-2026-87802/index.md)","id":"CVE-2026-87802","markdown":"https://insights.sbomify.com/CVE-2026-87802/index.md","name":"CVE-2026-87802","record":{"aliases":["GHSA-mg52-7466-j5f7"],"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 forge JWTs to impersonate users and gain full access to proxied services if SRA OAuth2 is configured without a JWKS URI.","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-347","name":"Improper Verification of Cryptographic Signature"}],"description":"Improper verification of cryptographic signature vulnerability in Apache Syncope.\n\nWhen SRA is configured for OAuth 2.0 without JWKS set URI assigned, an attacker can forge arbitrary JWTs to impersonate any user identity and permissions, gaining full access to services proxied by SRA.\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: SRA OAuth2 JWT signature verification bypass","id":"CVE-2026-87802","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":"Missing authorization in countly-server","id":"CVE-2026-87803"},"packages":[],"prev":{"headline":"IBM Cyber Fraud includes components with multiple known vulnerabilities","id":"CVE-2026-87800"},"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 forge JWTs to impersonate users and gain full access to proxied services if SRA OAuth2 is configured without a JWKS URI.","url":"https://insights.sbomify.com/CVE-2026-87802/"}
