Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Airflow's apache-airflow-providers-google package, versions before 22.6.0, builds Google Drive search queries by inserting file and folder names into single-quoted strings without escaping apostrophes. An attacker who can create objects in a bucket used by a wildcard gcs_to_gdrive transfer, or otherwise supply names to the Drive hook, can add clauses to the query. This can redirect uploads into an attacker-named folder or make downloads return an attacker-placed file. Upgrade to apache-airflow-providers-google 22.6.0 or later, which escapes these values.
