AI-suggested
Users should upgrade Apache Airflow to version 1.4.0 or later, where the issue is fixed. For deployments unable to upgrade immediately, setting 'secrets.use_cache = False' disables the vulnerable caching mechanism and mitigates the risk.
Description
Apache Airflow's Task SDK secret cache built its keys from the team name and secret id with unescaped `_` delimiters, so different (team, secret id) pairs could collide. In multi-team deployments a Dag author could read another team's Variable or Connection value by crafting a colliding secret id. Only deployments with both `core.multi_team = True` and `secrets.use_cache = True` are affected. Users are advised to upgrade to apache-airflow 3.4.0 or later. Deployments that cannot upgrade can set `secrets.use_cache = False`.
