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-2026-126257 in the wild and no public exploit code.\nExposure: Having an affected version installed is enough. The problem is in what it ships or how it installs, so no code has to call it.\n\nAffected product: Fortinet FortiAuthenticator. 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-2026-126257/ (Markdown: https://insights.sbomify.com/CVE-2026-126257/index.md)","id":"CVE-2026-126257","markdown":"https://insights.sbomify.com/CVE-2026-126257/index.md","name":"CVE-2026-126257","record":{"aliases":["GHSA-3jjw-p738-9hj8"],"analysis":{"component_type":"network_device","exploitable_when_present":true,"fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"authentication appliance","requires_auth":"none","requires_specific_call":false,"summary":"A hard-coded password in FortiAuthenticator may let unauthenticated attackers bypass credential checks and gain unauthorized access.","user_interaction":"not_required","vuln_class":"hardcoded_credentials","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"fortinet","cpe":[],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-259","name":"Use of Hard-coded Password"}],"description":"A use of hard-coded password vulnerability in Fortinet FortiAuthenticator 8.0.0 through 8.0.3, FortiAuthenticator 6.6.0 through 6.6.10 may allow an unauthenticated attacker to bypass credential validation in certain circumstances outside of the attacker's control and gain unauthorized access.","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":"Hardcoded credentials in FortiAuthenticator","id":"CVE-2026-126257","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"hardcoded_credentials","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in FortiOS","id":"CVE-2026-126258"},"nickname":null,"packages":[],"prev":{"headline":"Memory corruption in FortiOS","id":"CVE-2026-126256"},"products":["FortiAuthenticator"],"published":"2026-11-11","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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-11-11","vendors":["Fortinet"]},"summary":"A hard-coded password in FortiAuthenticator may let unauthenticated attackers bypass credential checks and gain unauthorized access.","url":"https://insights.sbomify.com/CVE-2026-126257/"}
