An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2025-59718 in the wild since at least 16 Dec 2025.\n\nAffected product: Fortinet Fortios. 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-2025-59718/ (Markdown: https://insights.sbomify.com/CVE-2025-59718/index.md)","id":"CVE-2025-59718","markdown":"https://insights.sbomify.com/CVE-2025-59718/index.md","name":"CVE-2025-59718","record":{"aliases":["GHSA-fjj2-p33c-f8qq"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Fortinet network security","requires_auth":"none","summary":"An unauthenticated attacker can bypass FortiCloud SSO login authentication by sending a crafted SAML response, gaining unauthorized access to Fortinet devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortios","vendor":"fortinet"},{"product":"fortiproxy","vendor":"fortinet"},{"product":"fortiswitchmanager","vendor":"fortinet"},{"product":"ruggedcom_ape1808_firmware","vendor":"siemens"}],"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:H/E:F/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"A improper verification of cryptographic signature vulnerability in Fortinet FortiOS 7.6.0 through 7.6.3, FortiOS 7.4.0 through 7.4.8, FortiOS 7.2.0 through 7.2.11, FortiOS 7.0.0 through 7.0.17, FortiProxy 7.6.0 through 7.6.3, FortiProxy 7.4.0 through 7.4.10, FortiProxy 7.2.0 through 7.2.14, FortiProxy 7.0.0 through 7.0.21, FortiSwitchManager 7.2.0 through 7.2.6, FortiSwitchManager 7.0.0 through 7.0.5 allows an unauthenticated attacker to bypass the FortiCloud SSO login authentication via a crafted SAML response message.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-12-17","github_poc":2,"max_poc_stars":6,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-12-17T11:33:22Z","kind":"github_poc","ref":"https://github.com/exfil0/CVE-2025-59718-PoC","stars":6,"title":"Fortinet announced two closely related authentication‑bypass vulnerabilities on 9 December 2025.
