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.
