CVE-2026-19594
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk32th percentile - higher than 32% of all known CVEs
Summary
The Snowflake Python API (`snowflake.core`) before version 1.13.0 has insufficient input sanitization, allowing confused-deputy privilege escalation through path traversal and HTTP parameter pollution. An attacker controlling an identifier or object name in an application using snowflake.core can perform operations on parent resources or override constraints on swap, clone, or rename operations in a higher-privileged session.
Risk Assessment
An attacker can exploit the application's privileged session to perform unauthorized operations on Snowflake data, potentially leading to data confidentiality and integrity breaches.
Recommendation
Upgrade Snowflake Python API to version 1.13.0 or later, which includes fixes.
Original NVD description (English source)
Insufficient input sanitization in Snowflake Python API (`snowflake.core`) versions prior to 1.13.0 allowed confused-deputy privilege escalation through two related weaknesses: path traversal (CWE-22) via unencoded `..` identifier path segments, and HTTP parameter pollution (CWE-141) via unencoded `&`/`#`/`=` characters in query string values. An attacker with access to a downstream application built on snowflake.core could exploit the path traversal by supplying `..` as an object name, causing `snowflake.core` to issue REST requests against a parent resource or exploit the parameter pollution by injecting `&`/`#`/`=` into a free-form name field to override constraints on swap, clone, or rename operations — all executed under the application's privileged session. Successful exploitation requires the attacker to control an identifier or object-name string in an application built on snowflake.core that passes it to `snowflake.core` under a higher-privileged Snowflake session (e.g., an EXECUTE AS OWNER stored procedure, Streamlit app, or Native App). The fix is available in Snowflake Python API version 1.13.0, which also addresses several additional security findings. Users must manually upgrade.
