Snowflake Php Pdo Driver
Monthly
Workload Identity Federation authentication in all major Snowflake client drivers transmits cloud attestation tokens to the configured host without first verifying that host is a recognized Snowflake endpoint, enabling token exfiltration and replay. An attacker who can modify connection configuration redirects the driver to an attacker-controlled server, which receives a freshly minted cloud workload-identity token that can be replayed against real Snowflake accounts for the token's remaining lifetime. On Azure, the attack surface is wider: the driver also fetches a Managed Identity access token scoped to an arbitrary Azure resource chosen by the attacker, extending potential impact beyond Snowflake to any Azure service that workload identity can reach. No public exploit has been identified at time of analysis, but vendor-confirmed patches were released September 3, 2026 across all eight affected driver packages.
Sensitive credential material - including authentication tokens, query-result encryption keys, pre-signed cloud-storage URLs, and SAML assertions - was written to diagnostic log files across six Snowflake client drivers (Python, Go, JDBC, Node.js, PHP PDO, and ODBC) due to incomplete log-redaction coverage. An attacker with read access to the log destination, whether a local filesystem, a log aggregation pipeline, or a CI/CD artifact store, can extract valid credentials and decryption keys. Exploitation impact is bounded by credential lifetime and object scope, but successful use of harvested tokens provides authenticated access to the corresponding Snowflake account or cloud-storage objects. No public exploit is identified at time of analysis; vendor-released patches are available for all six drivers as of September 3, 2026.
