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-2026-0234 in the wild and no public exploit code.\n\nAffected product: Palo Alto Networks Cortex XSIAM Microsoft Teams Marketplace. 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-2026-0234/ (Markdown: https://insights.sbomify.com/CVE-2026-0234/index.md)","id":"CVE-2026-0234","markdown":"https://insights.sbomify.com/CVE-2026-0234/index.md","name":"CVE-2026-0234","record":{"aliases":["GHSA-w48x-mvpf-jfc3"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Cortex XSOAR integration","requires_auth":"none","summary":"An unauthenticated attacker can bypass cryptographic signature verification in the Microsoft Teams integration to access and modify protected resources.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"palo_alto","cpe":[{"product":"cortex_xsiam","vendor":"paloaltonetworks"},{"product":"cortex_xsoar","vendor":"paloaltonetworks"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/AU:N/R:U/V:D/RE:M/U:Red","version":"4.0"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"An improper verification of cryptographic signature vulnerability exists in Cortex XSOAR and Cortex XSIAM platforms during integration of Microsoft Teams that enables an unauthenticated user to access and modify protected resources.","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":"Cortex XSOAR: Improper Verification of Cryptographic Signature in Microsoft Teams integration","id":"CVE-2026-0234","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Prisma Browser: Access and Data Rule Bypass","id":"CVE-2026-0235"},"packages":[],"prev":{"headline":"Autonomous Digital Experience Manager: Improper validation of ADEM certificate","id":"CVE-2026-0233"},"products":["Cortex XSIAM Microsoft Teams Marketplace","Cortex XSOAR Microsoft Teams Marketplace"],"published":"2026-04-13","related":[],"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":"2026-04-14","vendors":["Palo Alto Networks"]},"summary":"An unauthenticated attacker can bypass cryptographic signature verification in the Microsoft Teams integration to access and modify protected resources.","url":"https://insights.sbomify.com/CVE-2026-0234/"}
