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-2026-0263 in the wild and no public exploit code.\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-2026-0263/ (Markdown: https://insights.sbomify.com/CVE-2026-0263/index.md)","id":"CVE-2026-0263","markdown":"https://insights.sbomify.com/CVE-2026-0263/index.md","name":"CVE-2026-0263","record":{"aliases":["GHSA-xqxf-q4xj-jxh3"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PAN-OS firewall","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary code with elevated privileges or cause denial of service via buffer overflow in PAN-OS IKEv2 processing.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"palo_alto","cpe":[{"product":"pan-os","vendor":"paloaltonetworks"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:N/E:U/AU:Y/R:U/V:C/RE:H/U:Red","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A buffer overflow vulnerability in the IKEv2 processing of Palo Alto Networks PAN-OS® software allows an unauthenticated network-based attacker to execute arbitrary code with elevated privileges on the firewall, or cause a denial of service (DoS) condition.\n\nPanorama, Cloud NGFW, and Prisma® Access are not impacted by these vulnerabilities.","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":"PAN-OS: Remote Code Execution (RCE) in IKEv2 Processing","id":"CVE-2026-0263","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"paloaltonetworks:pan-os","products":["paloaltonetworks:pan-os"],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"PAN-OS: Heap-Based Buffer Overflow in DNS Proxy and DNS Server Allows Unauthenticated Remote Code Execution","id":"CVE-2026-0264"},"packages":[],"prev":{"headline":"PAN-OS: Denial of Service Vulnerabilities in Network Traffic Parsing","id":"CVE-2026-0262"},"products":["Cloud NGFW","PAN-OS","Prisma Access"],"published":"2026-05-13","related":[{"cvss_score":10,"headline":"Palo Alto Networks PAN-OS Command Injection","id":"CVE-2024-3400","kev_date_added":"2024-04-12","published":"2024-04-12"},{"cvss_score":10,"headline":"Palo Alto Networks PAN-OS Authentication Bypass","id":"CVE-2020-2021","kev_date_added":"2022-03-25","published":"2020-06-29"},{"cvss_score":9.8,"headline":"Palo Alto Networks PAN-OS Remote Code Execution","id":"CVE-2017-15944","kev_date_added":"2022-08-18","published":"2017-12-11"},{"cvss_score":9.3,"headline":"Palo Alto Networks PAN-OS Out-of-bounds Write","id":"CVE-2026-0300","kev_date_added":"2026-05-06","published":"2026-05-06"},{"cvss_score":9.3,"headline":"Palo Alto Networks PAN-OS Management Interface Authentication Bypass","id":"CVE-2024-0012","kev_date_added":"2024-11-18","published":"2024-11-18"},{"cvss_score":9.2,"headline":"PHP Memory Corruption","id":"CVE-2026-109618","kev_date_added":"2026-10-26","published":"2026-10-21"},{"cvss_score":9.2,"headline":"PHP Stale Internal Request-State","id":"CVE-2026-109619","kev_date_added":"2026-10-26","published":"2026-10-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-05-14","vendors":["Palo Alto Networks"]},"summary":"Unauthenticated attackers can execute arbitrary code with elevated privileges or cause denial of service via buffer overflow in PAN-OS IKEv2 processing.","url":"https://insights.sbomify.com/CVE-2026-0263/"}
