Apache Airflow 3.0.x Exposed JWTs Through Logout and Logging Flaws
Apache disclosed two JWT-related vulnerabilities in Apache Airflow affecting versions 3.0.0 before 3.2.0. The first, CVE-2025-57735, is a low-severity flaw in which logout did not invalidate authentication JWTs, leaving intercepted tokens usable after a user signed out. The second, CVE-2026-31987, is a moderate-severity issue that caused task JWTs to appear in logs, potentially exposing credentials to users who could then act as DAG authors.
Apache said both issues are fixed in Airflow 3.2.0, which adds token invalidation on logout and removes the logging exposure. Organizations running affected releases have been advised to upgrade to 3.2.0 or later, particularly where shared log access or concerns about token reuse could increase the risk of unauthorized access and privilege escalation.

Apache discloses CVE-2026-31987 for JWT tokens exposed in Airflow logs
Apache disclosed a moderate-severity vulnerability affecting Airflow versions 3.0.0 before 3.2.0 in which JWT tokens used by tasks could appear in logs. Apache said the issue could enable UI users to act as DAG authors and advised upgrading to Airflow 3.2.0.
Apache discloses CVE-2025-57735 affecting Airflow JWT logout behavior
Apache disclosed a low-severity vulnerability in Apache Airflow where authentication JWTs were not invalidated on logout, creating a risk that intercepted tokens could be reused. Users were advised to upgrade to Airflow 3.2.0 or later.
Apache Airflow 3.2.0 fixes JWT logout invalidation issue
Apache stated that Airflow 3.2 introduced token invalidation on logout, addressing CVE-2025-57735, which affected versions 3.0.0 before 3.2.0 and allowed JWTs to remain valid after logout.

Apache Airflow Flaws Enable Security Bypass and Multiple Additional Vulnerabilities
German authorities issued advisories for **Apache Airflow** covering a vulnerability that can bypass security measures and a separate notice for **multiple vulnerabilities** affecting the workflow orchestration platform. The alerts indicate that Airflow deployments may be exposed to weaknesses that undermine intended protections and introduce additional security risk across affected environments. Organizations using Apache Airflow should review the referenced advisories, identify affected versions, and prioritize vendor-recommended updates or mitigations. Because Airflow is commonly used to manage automated data pipelines and scheduled jobs, successful exploitation could weaken access controls or expose connected systems and workflows to further compromise.

Apache Airflow fixes XCom-related code execution flaws in deserialization and example DAGs
Apache disclosed two low-severity code execution issues in **Apache Airflow** tied to its XCom mechanism and addressed them in **Airflow 3.2.0**. **CVE-2026-33858** affects Airflow versions `3.1.8` before `3.2.0` and stems from unsafe deserialization in the XCom API, where legacy serialization keys `__type` and `__var` can bypass protections and let a DAG author craft payloads that execute arbitrary code in the webserver context. Apache said the flaw was rated low severity because DAG authors are already treated as highly trusted users. Apache also disclosed **CVE-2025-54550**, a low-severity remote code execution issue involving the documented `example_xcom` DAG pattern. The vulnerable pattern read XCom values in a way that could allow a UI user with permission to modify XComs to trigger arbitrary code execution on a worker through a race condition. Apache said official releases were not directly affected because example DAGs are not meant to be enabled in production, but organizations that copied the documented approach could reproduce the weakness in their own deployments; updated documentation in **Airflow 3.2.0** provides a safer example.

Multiple Vulnerabilities Disclosed in Apache HTTP Server and Apache Airflow Providers
German authorities published advisories for **multiple vulnerabilities** affecting both **Apache HTTP Server** and **Apache Airflow** components, expanding the list of enterprise Apache software requiring review. One notice, `dCERT Advisory 2026-1331`, covers several flaws in Apache HTTP Server, a widely deployed web server used in internet-facing and internal application environments. A separate notice, `dCERT Advisory 2026-1636`, reports multiple vulnerabilities in **Apache Airflow** provider packages, specifically the **Google** and **FAB** providers. While the advisories provided no public synopsis in the referenced notices, the disclosures indicate that organizations using these Apache products should identify affected deployments, review vendor guidance, and prioritize patching or other mitigations for exposed systems and workflow orchestration environments.
