CVE-2026-59245

In the Apache Airflow FAB auth manager, a DAG whose dagid is DAGs collided with the global all-DAGs permission resource name produced by resourcename, so a user granted per-DAG accesscontrol on that one DAG was silently granted the global all-DAGs permission privilege escalation. The escalation...

CVE-2026-58065

The Apache Airflow Git provider runs its git-over-SSH operations with StrictHostKeyChecking=no by default, disabling SSH host-key verification. An attacker who can intercept the network path between an Airflow worker and the Git server can impersonate the server man-in-the-middle, capturing the S...

PYSEC-2026-3049 Recce server has unauthenticated SQL execution that allows local file read/write through DuckDB

Impact Recce OSS server deployments that expose the server to an untrusted network without authentication are vulnerable to unauthenticated SQL execution through the query run API. When Recce is configured with a DuckDB-backed project, an attacker can use DuckDB filesystem primitives to read and...

Flawfinder output manipulation via untrusted filenames and source text

ImpactThis vulnerability is an improper input neutralization issue leading to output manipulation, specifically, Terminal/ANSI Escape Sequence Injection and XML Injection: Terminal Output Spoofing: A malicious file whose name contains ANSI escape sequences can end up being included in flawfinder'...

PYSEC-2026-2872 PGHoard: Password written to debug log

Impact When using .pgpass, database connection information including the username and password will be logged at the debug level. Patches Upgrade to version 2.7.1 or greater. Workarounds Filter out debug-level logs. References This issue was discovered by BugCrowd user DRAKOKORIAN...

PYSEC-2026-2510 Hermes Agent contains a DNS rebinding vulnerability in WebSocket endpoints that allows remote attackers to bypass Host and Origin validation

Hermes Agent before 0.16.0 contains a DNS rebinding vulnerability in WebSocket endpoints that allows remote attackers to bypass Host and Origin validation. FastAPI HTTP middleware does not execute for WebSocket upgrade requests on /api/pty, /api/ws, /api/pub, and /api/events endpoints, enabling...

PYSEC-2026-3431 yt-dlp: File Downloader cookie leak with curl

Summary If curl is used an external downloader for yt-dlp, cookies may be leaked to an unintended host upon HTTP redirect or when the host for download fragments differs from their parent manifest's. This is the equivalent to GHSA-v8mc-9377-rwjj for the curl downloader. The vulnerable behavior is...

pypdf: Possible long runtimes for zero-only width values in cross-reference streamsuntimes for zero-only width values in cross-reference streams

ImpactAn attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires cross-reference streams with /W 0 0 0 values and large /Size values. PatchesThis has been fixed in pypdf==6.12.0. WorkaroundsIf developers are unable to upgrade their apps immediately, they...

PYSEC-2026-3435 python-zeroconf: Unbounded TC-deferred queue allows LAN-local memory exhaustion via spoofed-source flood

Impact AsyncListener.handlequeryordefer retained every truncated TC-bit incoming query in self.deferredaddr and armed a per-addr timer in self.timersaddr that flushed the reassembled query within 500 ms RFC 6762 §18.5. Neither the per-addr list nor the number of distinct addr keys was capped, and...

PYSEC-2026-2456 Docling Core: Insufficient validation of image reference URIs

Impact In versions = 2.5.0, = 2.74.1 Workarounds If upgrading is not immediately possible: - reject file: and data: image references from untrusted input - allow only approved local or remote image sources - apply input size and memory limits to processing workers References - Fix release: v2.74....

PYSEC-2026-2457 Docling Core: Unsafe remote filename resolution

Impact In versions = 1.5.0, = 2.74.1 Workarounds If upgrading is not immediately possible, avoid passing untrusted URLs into remote fetch functionality. References - Fix release: v2.74.1...

PYSEC-2026-2354 Apache Airflow has an Authorization Bypass Through User-Controlled Key

The Event Log detail endpoint GET /api/v2/eventLogs/eventlogid in Apache Airflow fetched audit-log rows directly by numeric ID after only the generic Audit Log permission check, while the collection endpoint GET /api/v2/eventLogs applied per-Dag scoping. An authenticated UI/API user with audit-lo...

PYSEC-2026-2358 Apache Airflow: Execution API JWT leaked via KubernetesExecutor worker command-line args

A bug in Apache Airflow's KubernetesExecutor caused JWT tokens used by worker pods to authenticate against the Execution API to be passed to the worker container as command-line arguments visible in the pod spec. An authenticated UI/API user with Kubernetes read-only access to the cluster e.g...

PYSEC-2026-2349 Apache Airflow has an Improper Authorization issue

The structuredata endpoint in the Airflow UI returned external dependency graph nodes for linked Dags without checking whether the caller had read permission on those linked Dags. An authenticated UI/API user authorized for one Dag could enumerate linked Dag IDs and dependency metadata for other...

PYSEC-2026-2346 Apache Airflow has no certificate validation on SMTP STARTTLS connections

Apache Airflow's EmailOperator and the underlying airflow.utils.email helpers established SMTP STARTTLS connections without verifying the remote certificate when the deployment used email smtpstarttls=True without email smtpssl. An attacker positioned between the worker and the configured SMTP...

PYSEC-2026-2345 Apache Airflow: Authenticated users can bypass the `is_safe_url` check

A bug in the login redirect route in Apache Airflow allowed authenticated users to craft URLs that bypassed the issafeurl check, enabling redirection from a trusted Airflow domain to an attacker-controlled origin. Users are advised to upgrade to apache-airflow 3.2.2 or later. As a defense-in-dept...

zeroconf: Unbounded exception-dedup state retains packet buffers via traceback frame locals, enabling LAN-local memory exhaustion

ImpactDNSIncoming.logexceptiondebug and the four QuietLogger exception-dedup methods stored an unbounded seenlogs dict keyed by strsys.excinfo1. The seven IncomingDecodeError messages raised from readname / decodelabelsatoffset RFC 6762 §18 name-decoding error paths all embed self.source — the...

zeroconf has unbounded recursion in DNS compression-pointer decoder that allows LAN-local denial of service

ImpactDNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer RFC 1035 §4.1.4. Pointer cycles and label counts were capped, but the chain length of unique forward pointers was not. A single 3 kB mDNS packet carrying 1500 chained pointers drives the recursion past CPython's...
