An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-34063 exists.\n\nAffected product: OneLogin Active Directory Connector (ADC). 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-2025-34063/ (Markdown: https://insights.sbomify.com/CVE-2025-34063/index.md)","id":"CVE-2025-34063","markdown":"https://insights.sbomify.com/CVE-2025-34063/index.md","name":"CVE-2025-34063","record":{"aliases":["GHSA-g2mv-fq56-3w42"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OneLogin AD Connector","requires_auth":"none","summary":"Attackers can bypass authentication and impersonate users by exploiting an exposed JWT signing key, gaining unauthorized access to SSO portals and federated applications.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"A cryptographic authentication bypass vulnerability exists in OneLogin AD Connector prior to 6.1.5 due to the exposure of a tenant’s SSO JWT signing key via the /api/adc/v4/configuration endpoint. An attacker in possession of the signing key can craft valid JWT tokens impersonating arbitrary users within a OneLogin tenant. The tokens allow authentication to the OneLogin SSO portal and all downstream applications federated via SAML or OIDC. This allows full unauthorized access across the victim’s SaaS environment.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"OneLogin AD Connector JWT Authentication Bypass via Exposed Signing Key","id":"CVE-2025-34063","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"OneLogin AD Connector Log S3 Bucket Hijack Leading to Cross-Tenant Data Leakage","id":"CVE-2025-34064"},"packages":[],"prev":{"headline":"OneLogin AD Connector API Credential and Signing Key Exposure","id":"CVE-2025-34062"},"products":["OneLogin Active Directory Connector (ADC)"],"published":"2025-07-01","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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-07-01","vendors":["One Identity"]},"summary":"Attackers can bypass authentication and impersonate users by exploiting an exposed JWT signing key, gaining unauthorized access to SSO portals and federated applications.","url":"https://insights.sbomify.com/CVE-2025-34063/"}
