Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-3259 in the wild and no public exploit code.\n\nAffected product: Google Cloud BigQuery. 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-2026-3259/ (Markdown: https://insights.sbomify.com/CVE-2026-3259/index.md)","id":"CVE-2026-3259","markdown":"https://insights.sbomify.com/CVE-2026-3259/index.md","name":"CVE-2026-3259","record":{"aliases":["GHSA-g3wg-j2ff-prcp"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Google BigQuery","requires_auth":"low_privilege","summary":"An authenticated user can disclose sensitive data via crafted materialized view error messages in Google BigQuery.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GoogleCloud","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/U:Clear","version":"4.0"},"cwes":[{"id":"CWE-209","name":"Generation of Error Message Containing Sensitive Information"}],"description":"A Generation of Error Message Containing Sensitive Information vulnerability in the Materialized View Refresh mechanism in Google BigQuery on Google Cloud Platform allows an authenticated user to potentially disclose sensitive data using a crafted materialized view that triggers a runtime error during the refresh process.\n\nThis vulnerability was patched on 29 January 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":"Sensitive Data Disclosure in BigQuery via Materialized View Error Messages","id":"CVE-2026-3259","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Undertow: Denial of Service via Multipart/Form-Data Parsing on HTTP GET Requests","id":"CVE-2026-3260"},"packages":[],"prev":{"headline":"UnQLite versions through 0.06 for Perl uses a potentially insecure version of the UnQLite library","id":"CVE-2026-3257"},"products":["BigQuery"],"published":"2026-04-23","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":"partial"},"state":"PUBLISHED","updated":"2026-04-30","vendors":["Google Cloud"]},"summary":"An authenticated user can disclose sensitive data via crafted materialized view error messages in Google BigQuery.","url":"https://insights.sbomify.com/CVE-2026-3259/"}
