An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-18577 in the wild since at least 3 Aug 2026.\n\nAffected product: N-able N-central. 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-2026-18577/ (Markdown: https://insights.sbomify.com/CVE-2026-18577/index.md)","id":"CVE-2026-18577","markdown":"https://insights.sbomify.com/CVE-2026-18577/index.md","name":"CVE-2026-18577","record":{"aliases":["GHSA-qgcm-97x5-6q8q"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"N-central management software","requires_auth":"none","summary":"Attackers can bypass authentication to take over administrative accounts in N-central due to an incomplete security patch.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"N-able","cpe":[{"product":"n-central","vendor":"n-able"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:L/SI:L/SA:L/E:A","version":"4.0"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"An incomplete patch for CVE-2026-18556 allows for authentication bypass and account takeover in N-central Versions through 2026.3.1","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-08-04","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":1,"refs":[{"date":"2026-08-04T07:43:25Z","kind":"github_poc","ref":"https://github.com/HORKimhab/CVE-2026-18577","stars":0,"title":"CVE-2026-18577 - Draft"},{"date":null,"kind":"nuclei","ref":"http/cves/2026/CVE-2026-18577.yaml","stars":null,"title":"N-able N-central \u003c 2026.3.1.10 - Authentication Bypass"}],"tier":"exploited"},"has_fix":null,"headline":"N-able N-central Authentication Bypass Using an Alternate Path or Channel","id":"CVE-2026-18577","indexable":true,"kev":{"dateAdded":"2026-08-03","dueDate":"2026-08-06","knownRansomwareCampaignUse":"Unknown","product":"N-central","requiredAction":"Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes).
