An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-0266 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-2026-0266/ (Markdown: https://insights.sbomify.com/CVE-2026-0266/index.md)","id":"CVE-2026-0266","markdown":"https://insights.sbomify.com/CVE-2026-0266/index.md","name":"CVE-2026-0266","record":{"aliases":["GHSA-3xrx-45h3-29cm"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"PAN-OS firewall","requires_auth":"high_privilege","summary":"A malicious authenticated administrator can store JavaScript payloads in the PAN-OS web interface, potentially compromising other administrators.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"palo_alto","cpe":[{"product":"pan-os","vendor":"paloaltonetworks"}],"cvss":{"score":1.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/AU:N/R:U/V:D/RE:M/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A cross-site scripting (XSS) vulnerability in Palo Alto Networks PAN-OS® software enables a malicious authenticated administrator to store a JavaScript payload using the web interface. \n\nThis issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series).\n\nCloud NGFW and Prisma® Access are not affected by this vulnerability.","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: Stored Cross-Site Scripting (XSS) Vulnerability in the Web Interface","id":"CVE-2026-0266","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"paloaltonetworks:pan-os","products":["paloaltonetworks:pan-os"],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"GlobalProtect App: Information Exposure Vulnerability on macOS","id":"CVE-2026-0267"},"packages":[],"prev":{"headline":"PAN-OS: Authentication Bypass with Cloud Authentication Service (CAS) enabled","id":"CVE-2026-0265"},"products":["Cloud NGFW","PAN-OS","Prisma Access"],"published":"2026-06-10","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":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["Palo Alto Networks"]},"summary":"A malicious authenticated administrator can store JavaScript payloads in the PAN-OS web interface, potentially compromising other administrators.","url":"https://insights.sbomify.com/CVE-2026-0266/"}
