An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-24858 in the wild since at least 27 Jan 2026.\n\nAffected product: Fortinet Fortianalyzer. 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-2026-24858/ (Markdown: https://insights.sbomify.com/CVE-2026-24858/index.md)","id":"CVE-2026-24858","markdown":"https://insights.sbomify.com/CVE-2026-24858/index.md","name":"CVE-2026-24858","record":{"aliases":["GHSA-2x38-48vp-w23x"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Fortinet network appliances","requires_auth":"none","summary":"Attackers with FortiCloud accounts can bypass authentication to access other users' devices if FortiCloud SSO is enabled.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortianalyzer","vendor":"fortinet"},{"product":"fortimanager","vendor":"fortinet"},{"product":"fortinac-f","vendor":"fortinet"},{"product":"fortios","vendor":"fortinet"},{"product":"fortiproxy","vendor":"fortinet"},{"product":"fortiweb","vendor":"fortinet"},{"product":"ruggedcom_ape1808_firmware","vendor":"siemens"}],"cvss":{"score":9.4,"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:H/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"An Authentication Bypass Using an Alternate Path or Channel vulnerability [CWE-288] vulnerability in Fortinet FortiAnalyzer 7.6.0 through 7.6.5, FortiAnalyzer 7.4.0 through 7.4.9, FortiAnalyzer 7.2.0 through 7.2.11, FortiAnalyzer 7.0.0 through 7.0.15, FortiManager 7.6.0 through 7.6.5, FortiManager 7.4.0 through 7.4.9, FortiManager 7.2.0 through 7.2.11, FortiManager 7.0.0 through 7.0.15, FortiNAC-F 7.6.3 through 7.6.5, FortiOS 7.6.0 through 7.6.5, FortiOS 7.4.0 through 7.4.10, FortiOS 7.2.0 through 7.2.12, FortiOS 7.0.0 through 7.0.18, FortiProxy 7.6.0 through 7.6.4, FortiProxy 7.4.0 through 7.4.12, FortiProxy 7.2.0 through 7.2.15, FortiProxy 7.0.0 through 7.0.22, FortiWeb 8.0.0 through 8.0.3, FortiWeb 7.6.0 through 7.6.6, FortiWeb 7.4.0 through 7.4.11 may allow an attacker with a FortiCloud account and a registered device to log into other devices registered to other accounts, if FortiCloud SSO authentication is enabled on those devices.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-01-28","github_poc":5,"max_poc_stars":9,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-01-30T03:29:04Z","kind":"github_poc","ref":"https://github.com/absholi7ly/CVE-2026-24858-FortiCloud-SSO-Authentication-Bypass","stars":9,"title":"CVE-2026-24858 FortiCloud Single Sign On (SSO)  a factory default enabled feature once you register any FortiGate/FortiManager/FortiAnalyzer  contains a critical authentication bypass flaw."},{"date":"2026-02-10T17:51:07Z","kind":"github_poc","ref":"https://github.com/gagaltotal/cve-2026-24858","stars":1,"title":"CVE-2026-24858 - Administrative FortiCloud SSO authentication bypass"},{"date":"2026-01-28T14:34:50Z","kind":"github_poc","ref":"https://github.com/m0d0ri205/CVE-2026-24858","stars":0,"title":"아직 제로데이인거 같아, 공개되거나 천천히 분석할 예정...."},{"date":"2026-01-30T04:27:24Z","kind":"github_poc","ref":"https://github.com/SimoesCTT/-CTT-NSP-Convergent-Time-Theory---Network-Stack-Projection-CVE-2026-24858-","stars":0,"title":" A Proof-of-Concept demonstrating the application of 3D Navier-Stokes CTT formulations to packet flow optimization and defensive bypass."},{"date":"2026-01-31T09:41:04Z","kind":"github_poc","ref":"https://github.com/SimoesCTT/SCTT-2026-33-0004-FortiCloud-SSO-Identity-Singularity","stars":0,"title":"While Fortinet's January 27, 2026 mitigation for **CVE-2026-24858** focuses on blocking specific accounts like `cloud-noc@mail.io`, it fails to address the **Temporal Vulnerability** of the SAML state machine.
