An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-111227 exists.\n\nAffected product: Netgate pfSense CE. 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-2026-111227/ (Markdown: https://insights.sbomify.com/CVE-2026-111227/index.md)","id":"CVE-2026-111227","markdown":"https://insights.sbomify.com/CVE-2026-111227/index.md","name":"CVE-2026-111227","record":{"aliases":["GHSA-4m9r-jxrh-x66q"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"pfSense CE","requires_auth":"high_privilege","summary":"Authenticated users can inject CRLF characters to manipulate DNS resolver configuration, allowing control over DNS answers served to LAN clients.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"pfsense","vendor":"pfsense"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:L/SC:N/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"}],"description":"Netgate pfSense CE through 2.9.0 contains a CRLF injection vulnerability in services_unbound_acls.php that allows authenticated users with the DNS Resolver: Access Lists privilege to inject Unbound configuration directives.
