Apache Airflow Providers Snowflake: Failure to Sanitize Special Elements into a Different Plane

Published Updated By the CyberSecBulletin desk

CVE-2025-50213 is a critical-severity failure to sanitize special elements into a different plane vulnerability in Apache Airflow Providers Snowflake from Apache, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 6.4.0 as the first without the flaw, so updating Apache Airflow Providers Snowflake to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.77% chance of exploitation within 30 days, higher than 56% of scored CVEs.
