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-2026-85267/ (Markdown: https://insights.sbomify.com/CVE-2026-85267/index.md)","id":"CVE-2026-85267","markdown":"https://insights.sbomify.com/CVE-2026-85267/index.md","name":"CVE-2026-85267","record":{"aliases":["GHSA-342c-3cqc-4gph"],"analysis":null,"analysis_generated_by":null,"assigner":"GoogleCloud","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L/U:Clear","version":"4.0"},"cwes":[{"id":"CWE-1385","name":"Missing Origin Validation in WebSockets"}],"description":"A Cross-Site WebSocket Hijacking vulnerability in Cloud Shell prior to 2026-07-22 on Google Cloud Platform allows an unauthenticated attacker to hijack an active Cloud Shell session and exfiltrate the user's OAuth access token using a cross-origin WebSocket request.\n\nThis vulnerability was patched on 22 July 2026, and no customer action is needed.","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":"Cross-Site WebSocket Hijacking in Google Cloud Shell","id":"CVE-2026-85267","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in openedx-platform","id":"CVE-2026-85271"},"packages":[],"prev":{"headline":"Apache Camel: Camel-MLLP Protected Health Information Disclosure to Logs by Default","id":"CVE-2026-85260"},"products":["Cloud Shell"],"published":"2026-10-20","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-20","vendors":["Google Cloud"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-85267/"}
