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-2026-77549 in the wild and no public exploit code.\n\nAffected product: Ubiquiti Inc Cloud Gateways. 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-2026-77549/ (Markdown: https://insights.sbomify.com/CVE-2026-77549/index.md)","id":"CVE-2026-77549","markdown":"https://insights.sbomify.com/CVE-2026-77549/index.md","name":"CVE-2026-77549","record":{"aliases":["GHSA-g4h7-m732-3278"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"UniFi OS devices","requires_auth":"none","summary":"Attackers can bypass authentication on UniFi OS devices via CRLF injection, requiring network access and specific conditions.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Ubiquiti","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","version":"3.1"},"cwes":[{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"}],"description":"A malicious actor with access to the network and under certain conditions could exploit an Improper Neutralization of CRLF Sequences vulnerability found in certain devices running UniFi OS to bypass authentication to such UniFi OS devices or instances.","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":"Auth bypass in Cloud Gateways","id":"CVE-2026-77549","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in Cloud Gateways","id":"CVE-2026-77550"},"packages":[],"prev":{"headline":"Command injection in UniFi Protect Application","id":"CVE-2026-77548"},"products":["Cloud Gateways","Cloud Keys","Dream Machines","Dream Routers","Dream Wall","Enterprise Firewall Core","Enterprise Fortress Gateway","Enterprise Network Attached Storage","Enterprise Network Video Recorders","Express","Express 7","Network Attached Storage","Network Video Recorders","UniFi OS Server"],"published":"2026-08-26","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-27","vendors":["Ubiquiti Inc"]},"summary":"Attackers can bypass authentication on UniFi OS devices via CRLF injection, requiring network access and specific conditions.","url":"https://insights.sbomify.com/CVE-2026-77549/"}
