CVE-2026-81914 · Severity: low · CVSS 3.1 · Published 2026-09-29

Apache Airflow's Google Drive connector builds search queries by directly inserting file and folder names without escaping special characters. An attacker who can create objects in a storage bucket can inject malicious search terms into the query by naming files with apostrophes, allowing them to redirect uploads to attacker-controlled folders or trick downloads into returning attacker-supplied files instead of the intended data.

  ```


## Technical details

The vulnerability is a string injection flaw in the Google Drive query builder where file and folder names from external sources (such as GCS bucket listings) are interpolated directly into single-quoted query strings without escaping quote characters. An attacker can inject additional query clauses by using an apostrophe in a file/folder name to break out of the string literal. This affects wildcard gcs_to_gdrive transfers where bucket contents are controlled by lower-privileged principals, enabling file steering attacks.
