# CVE-2026-76185: Apache Airflow Task SDK: Task SDK SecretCache: non-injective team cache key enables cross-team secret disclosure in multi-team mode

- Also known as: EUVD-2026-119904
- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 1.4.0

CVE-2026-76185 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It affects Apache Airflow Task SDK; fixed in 1.4.0.

## Summary

Apache Airflow's Task SDK secret cache can let a Dag author in a multi-team deployment read another team's Variable or Connection value by crafting a colliding secret ID. Only deployments with both `core.multi_team` and `secrets.use_cache` enabled are affected, and that setup is not the default.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- apache-airflow-task-sdk (PyPI): from 1.2.0, fixed in 1.4.0

## 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`.
