An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-0257 in the wild since at least 29 May 2026, including in ransomware campaigns.\n\nAffected product: Paloaltonetworks Pan-Os. 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-2026-0257/ (Markdown: https://insights.sbomify.com/CVE-2026-0257/index.md)","id":"CVE-2026-0257","markdown":"https://insights.sbomify.com/CVE-2026-0257/index.md","name":"CVE-2026-0257","record":{"aliases":["GHSA-jqxw-84hx-6qj5"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"PAN-OS GlobalProtect","requires_auth":"none","summary":"Attackers can bypass authentication in PAN-OS GlobalProtect to establish unauthorized VPN connections, requiring immediate patching by network administrators.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"palo_alto","cpe":[{"product":"pan-os","vendor":"paloaltonetworks"},{"product":"prisma_access","vendor":"paloaltonetworks"},{"product":"ruggedcom_ape1808_firmware","vendor":"siemens"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:H/SI:H/SA:N/E:A/AU:N/R:A/V:D/RE:M/U:Red","version":"4.0"},"cwes":[{"id":"CWE-565","name":"Reliance on Cookies without Validation and Integrity Checking"}],"description":"Authentication bypass vulnerabilities in the GlobalProtect portal and gateway of Palo Alto Networks PAN-OS® software allows the attacker to bypass security restrictions and establish an unauthorized VPN connection.\n\nPanorama and Cloud NGFW are not impacted by these issues.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-05-29","github_poc":7,"max_poc_stars":30,"metasploit":0,"nuclei":1,"refs":[{"date":"2026-05-29T11:46:55Z","kind":"github_poc","ref":"https://github.com/sfewer-r7/CVE-2026-0257","stars":30,"title":"Proof-of-concept script to leverage the PAN-OS GlobalProtect authentication bypass CVE-2026-0257"},{"date":"2026-05-30T09:04:29Z","kind":"github_poc","ref":"https://github.com/0xredash/CVE-2026-0257","stars":3,"title":"CVE-2026-0257"},{"date":"2026-06-03T07:54:36Z","kind":"github_poc","ref":"https://github.com/tushargurav28/CVE-2026-0257","stars":3,"title":"Palo Alto Networks PAN-OS contains an authentication bypass caused by flaws in the GlobalProtect portal and gateway, letting attackers establish unauthorized VPN connections, exploit requires network access to the portal or gateway."},{"date":"2026-05-29T20:27:44Z","kind":"github_poc","ref":"https://github.com/akashsingh0454/CVE-2026-0257-PoC","stars":2,"title":null},{"date":"2026-06-10T07:34:30Z","kind":"github_poc","ref":"https://github.com/grayxploit/CVE-2026-0257","stars":2,"title":"GrayXploit Security research and defensive team validate this toolkit for CVE-2026-0257 (PAN-OS GlobalProtect Authentication Bypass).
