While MCP Toolbox utilizes an allowedDatasets mechanism to restrict queries, this defense only validates the history_data parameter; the final assembled query is executed without re-validation.\n\nAn attacker can break out of the string literal fields (such as timestamp_col) to inject a valid multi-statement or cross-dataset query block. This allows an unauthorized user to bypass the operator-configured allowedDatasets boundary and read arbitrary BigQuery tables.","published_at":"2026-07-21T16:39:54.968000Z","last_modified_at":"2026-07-22T19:16:55.480000Z","cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":8.6,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-89","CWE-863"],"nvd_references":["https://github.com/googleapis/mcp-toolbox/pull/3324"],"vuln_status":"Awaiting Analysis","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-07-21T18:40:10.196202Z","updated_at":"2026-07-22T22:41:08.814983Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"N","value_label":"None"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"google","vendor_name":"Google","product_slug":"mcp-toolbox-for-databases-googleapis-mcp-toolbox","product_name":"MCP Toolbox for Databases (googleapis/mcp-toolbox)","version_start":"0.13.0","version_start_inclusive":true,"version_end":"1.3.0","version_end_inclusive":true,"cpe23_uri":"cve5:google:mcp-toolbox-for-databases-googleapis-mcp-toolbox:0.13.0:1.3.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/googleapis/mcp-toolbox/pull/3324","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-07-21T16:39:54.968000Z","label":"CVE published","source":null},{"type":"ssvc_changed","at":"2026-07-22T19:46:53.962781Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-07-22T19:46:53.962781Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-07-22T19:46:53.962781Z","label":"SSVC decision revised","source":"vulnrichment"}]}
