CVE-2026-81914— Apache Airflow Google provider: Google Drive query injection via unescaped file and folder names

Quick assessment

Affected
Apache Software Foundation Apache Airflow Google provider
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Apache Airflow 的 Google 提供者（provider）在构建 Google Drive 搜索表达式时，直接将文件和文件夹名称插值到用单引号包裹的字符串字面量中，而未对用于分隔这些字面量的单引号字符进行转义。因此，如果名称中包含撇号（apostrophe，即 ），就会提前终止该字符串字面量，从而允许攻击者向查询中追加其自定义的子句。 这些名称通常并非由 DAG 作者直接编写。在通配符 传输任务中，名称来源于源 GCS 存储桶的对象列表。因此，任何能够在此存储桶中创建对象的主体都能控制这些名称——这

Vulnerability Title
Apache Airflow Google provider: Google Drive query injection via unescaped file and folder names
Source: CVE Program / CVE List V5
Vulnerability Description
Apache Airflow's Google provider built Google Drive search expressions by interpolating file and folder names directly into single-quoted string literals, without escaping the quote character that delimits them. A name containing an apostrophe therefore terminated the literal early and appended clauses of the attacker's choosing to the query. The names are frequently not written by the Dag author. In a wildcard `gcs_to_gdrive` transfer they come from the source bucket listing, so anyone able to create objects in that bucket controls them — typically an external data producer or an ingest-only service account, a different trust principal from the Dag author. An injected clause can broaden the match and so steer which file or folder the hook resolves: an upload can be directed into a folder the attacker named, and, because downloads select the most recently modified match, a download can return a file they placed rather than the one the Dag asked for. Affects deployments passing externally-sourced names to the Google Drive hook, including wildcard `gcs_to_gdrive` transfers from buckets writable by less-trusted principals. Users are advised to upgrade to `apache-airflow-providers-google` `22.6.0` or later, which escapes quote and backslash characters in every value interpolated into a Drive query.
