An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-50751 in the wild since at least 8 Jun 2026, including in ransomware campaigns.\n\nAffected product: checkpoint Quantum Security Gateway. 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-2026-50751/ (Markdown: https://insights.sbomify.com/CVE-2026-50751/index.md)","id":"CVE-2026-50751","markdown":"https://insights.sbomify.com/CVE-2026-50751/index.md","name":"CVE-2026-50751","record":{"aliases":["GHSA-jqxh-x9f5-wcgw"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Checkpoint Security Gateway","requires_auth":"none","summary":"Unauthenticated attackers can bypass user authentication in deprecated IKEv1 to establish remote access VPN connections without valid credentials.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"checkpoint","cpe":[{"product":"gaia_embedded","vendor":"checkpoint"},{"product":"gaia_os","vendor":"checkpoint"}],"cvss":{"score":9.3,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"A logic flow weakness in Remote Access and Mobile Access certificate validation in deprecated IKEv1 key exchange allows an unauthenticated remote attacker to bypass user authentication and establish a remote access VPN connection without a valid user password.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-08","github_poc":8,"max_poc_stars":7,"metasploit":0,"nuclei":1,"refs":[{"date":"2026-06-10T21:10:44Z","kind":"github_poc","ref":"https://github.com/watchtowrlabs/watchTowr-vs-Check-Point-CVE-2026-50751","stars":7,"title":null},{"date":"2026-06-08T14:35:04Z","kind":"github_poc","ref":"https://github.com/0xredash/CVE-2026-50751","stars":2,"title":"CVE-2026-50751"},{"date":"2026-06-08T13:26:38Z","kind":"github_poc","ref":"https://github.com/WadesWeaponShed/CVE-2026-50751-Mitigation-Scripts","stars":1,"title":"Mitigation scripts for CVE-2026-50751"},{"date":"2026-06-10T14:16:22Z","kind":"github_poc","ref":"https://github.com/fevar54/CVE-2026-50751---Check-Point-IKEv1-Authentication-Bypass-Exploit","stars":1,"title":"PoC de CVE-2026-50751: bypass de autenticacion IKEv1 en Check Point Remote/Mobile Access."},{"date":"2026-06-18T21:45:56Z","kind":"github_poc","ref":"https://github.com/WadesWeaponShed/CheckPoint-CVE-Webscanner","stars":1,"title":"A web version of the bash scripts wrote for Check Point CVE-2026-50751 and CVE-2026-50752.
