An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-2473 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- google-cloud-aiplatform (PyPI): affected from 1.21.0; fixed in 1.133.0\n- google-cloud-aiplatform (PyPI): affected from 1.21.0; fixed in 1.133.0\n- google-cloud-aiplatform (PyPI): affected from 1.21.0; fixed in 1.133.0\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-2026-2473/ (Markdown: https://insights.sbomify.com/CVE-2026-2473/index.md)","id":"CVE-2026-2473","markdown":"https://insights.sbomify.com/CVE-2026-2473/index.md","name":"CVE-2026-2473","record":{"aliases":["ECHO-1631-918e-c957","GHSA-wh2j-26j7-9728","MINI-2wx4-qm3x-w6h5","MINI-5hq6-jvqx-g877","MINI-74r4-hjh8-6jw4","PYSEC-2026-2500"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Vertex AI Experiments","requires_auth":"none","summary":"Unauthenticated attackers can achieve remote code execution and model theft by pre-creating predictable Cloud Storage buckets in Vertex AI Experiments.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GoogleCloud","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/U:Clear","version":"4.0"},"cwes":[{"id":"CWE-340","name":"Generation of Predictable Numbers or Identifiers"}],"description":"Predictable bucket naming in Vertex AI Experiments in Google Cloud Vertex AI from version 1.21.0 up to (but not including) 1.133.0 on Google Cloud Platform allows an unauthenticated remote attacker to achieve cross-tenant remote code execution, model theft, and poisoning via pre-creating predictably named Cloud Storage buckets (Bucket Squatting).\n\nThis vulnerability was patched and no customer action is needed.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Bucket Squatting in Vertex AI Experiments leads to RCE and Model Theft.","id":"CVE-2026-2473","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"other","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"Memory corruption in Crypt::URandom","id":"CVE-2026-2474"},"packages":[{"ecosystem":"PyPI","fixed":["1.133.0"],"introduced":["1.21.0"],"last_affected":[],"package":"google-cloud-aiplatform","purl":null,"source":"GHSA-wh2j-26j7-9728"},{"ecosystem":"PyPI","fixed":["1.133.0"],"introduced":["1.21.0"],"last_affected":[],"package":"google-cloud-aiplatform","purl":"pkg:pypi/google-cloud-aiplatform","source":"GHSA-wh2j-26j7-9728"},{"ecosystem":"PyPI","fixed":["1.133.0"],"introduced":["1.21.0"],"last_affected":[],"package":"google-cloud-aiplatform","purl":"pkg:pypi/google-cloud-aiplatform","source":"PYSEC-2026-2500"}],"prev":{"headline":"Stored Cross-Site Scripting (XSS) in Vertex AI Python SDK Visualization","id":"CVE-2026-2472"},"products":["Vertex AI Experiments"],"published":"2026-02-20","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"2026-02-23","vendors":["Google Cloud"]},"summary":"Unauthenticated attackers can achieve remote code execution and model theft by pre-creating predictable Cloud Storage buckets in Vertex AI Experiments.","url":"https://insights.sbomify.com/CVE-2026-2473/"}
