Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-126240 in the wild and no public exploit code.\nExposure: Only installations with a non-default setting turned on are exposed.\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-2026-126240/ (Markdown: https://insights.sbomify.com/CVE-2026-126240/index.md)","id":"CVE-2026-126240","markdown":"https://insights.sbomify.com/CVE-2026-126240/index.md","name":"CVE-2026-126240","record":{"aliases":["GHSA-hgh4-pcf2-8q3f"],"analysis":{"component_type":"server_software","exploitable_when_present":false,"fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"authentication server","requires_auth":"low_privilege","requires_specific_call":false,"summary":"An authenticated attacker controlling the upstream IdP name or SAML attribute can inject LDAP filters to bypass FortiAuthenticator authentication.","user_interaction":"not_required","vuln_class":"auth_bypass","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"fortinet","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-90","name":"Improper Neutralization of Special Elements used in an LDAP Query"}],"description":"A improper neutralization of special elements used in an ldap query ('ldap injection') vulnerability in Fortinet FortiAuthenticator 8.0.0 through 8.0.3, FortiAuthenticator 6.6.0 through 6.6.10 may allow an authenticated attacker to bypass authentication.
