PYSEC-2026-2603 Litestar: AllowedHostsMiddleware bypasses host validation via client-controlled X-Forwarded-Host header

Summary AllowedHostsMiddleware trusts the X-Forwarded-Host header as a fallback when the Host header is absent. Since X-Forwarded-Host is a client-controllable header, an attacker can bypass the allowed hosts validation by omitting the Host header and supplying an X-Forwarded-Host header set to a...

PYSEC-2026-2659 MLflow: Any authenticated user can enumerate all gateway secrets, endpoints, and model definitions

MLflow 3.9.0 with basic-auth --app-name basic-auth fails to enforce authorization checks for multiple Gateway API 'list' endpoints. Specifically, the BEFOREREQUESTHANDLERS dictionary in mlflow/server/auth/init.py does not include entries for ListGatewaySecretInfos, ListGatewayEndpoints, and...

PYSEC-2026-2532 Jupyter Server vulnerable to Path Traversal via incorrect root directory boundary check in _get_os_path()

A path traversal vulnerability exists in jupyter-server version 2.17.0 due to an incorrect root directory boundary check in the getospath function within jupyterserver/services/contents/fileio.py. The check uses startswithroot without appending a trailing path separator, allowing sibling...

CVE-2026-57432

Perl versions through 5.43.10 have an integer overflow in Smeasurestruct leading to an out-of-bounds heap read in pack and unpack. Smeasurestruct adds each item's size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the...

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-2026-2960 pretix vulnerable to Authorization Bypass Through User-Controlled Key

When creating an export through the pretix API, API clients are returned an UUID value for their export job a long, random string like 35742818-c375-4d15-839f-d49aecce94d6. Using this UUID, the API client can then request the actual file for download. The same kind of UUID is used in other places...

PYSEC-2026-2600 LiteLLM allows a user to modify their own user_role via the /user/update endpoint

LiteLLM prior to 1.83.10 allows a user to modify their own userrole via the /user/update endpoint. While the endpoint correctly restricts users to updating only their own account, it does not restrict which fields may be changed. A user who can reach this endpoint can set their role to proxyadmin...

PYSEC-2026-2478 Flask-Security-Too OAuth reauthentication freshness bypass via cross- user OAuth identity acceptance

Summary Flask-Security-Too 5.8.0's OAuth reauthentication flow can mark a session as fresh after verifying an OAuth account that belongs to a different user. If an attacker can operate an already-authenticated but stale victim session, they can complete OAuth verification using their own OAuth...

PYSEC-2026-2660 MLflow authenticated users can enumerate any registered model versions due to lack of per-model permissions checks

In mlflow/mlflow versions up to 3.9.0, the SearchModelVersions REST API endpoint and the mlflowSearchModelVersions GraphQL query lack proper per-model authorization checks when basic authentication is enabled. This allows any authenticated user to enumerate all model versions across all registere...

PYSEC-2026-2767 Open WebUI has an IDOR vulnerability in the update_message_by_id API endpoint

Summary An IDOR vulnerability exists in the Channels feature of Open WebUI, allowing any channel member to modify messages sent by other members including administrators within the same channel. This vulnerability affects the latest version v0.8.12 of Open WebUI. Details In the updatemessagebyid...

PYSEC-2026-2726 Open WebUI has Broken Access Control for Completions API

Summary Any user X can continue the conversation of any other user Y, as long as the Chat ID of Y is known. User X does not even need to be an admin to do so. Details A user just needs to use the API endpoint: /api/chat/completions with their own API key generated in OWUI and the Chat ID of anoth...

PYSEC-2026-3043 PyTorch Lightning load_from_checkpoint has an insecure checkpoint deserialization

PyTorch-Lightning versions 2.6.0 and earlier contain an insecure deserialization vulnerability CWE-502 in the checkpoint loading mechanism. The LightningModule.loadfromcheckpoint method, which is commonly used to load saved model states, internally calls torch.load without setting the...

PYSEC-2026-2993 PyLoad vulnerable to unauthenticated traceback disclosure via global exception handler in WebUI

Summary pyload-ng WebUI returns full Python traceback details to clients on unhandled exceptions. Because /web/ is reachable without authentication and renders attacker-controlled template names, an unauthenticated user can reliably trigger a server exception for example by requesting a...

PYSEC-2026-2894 PPTAgent: Arbitrary File Write via `save_generated_slides`

Summary This vulnerability has been fixed in https://github.com/icip-cas/PPTAgent/commit/418491a9a1c02d9d93194b5973bb58df35cf9d00. The savegeneratedslides MCP tool accepts a pptxpath argument and writes the generated PPTX file to that path without any workspace restriction or path validation:...

CVE-2026-59245 Apache Airflow FAB provider: FAB auth manager: a DAG named "DAGs" hijacks the global all-DAGs permission (access_control privilege escalation via resource_name() collision)

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...

PYSEC-2026-2351 Apache Airflow's authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop (HITL) and TaskInstance record

The authenticated /ui/dags endpoint did not enforce per-DAG access control on embedded Human-in-the-Loop HITL and TaskInstance records: a logged-in Airflow user with read access to at least one DAG could retrieve HITL prompts including their request parameters and full TaskInstance details for DA...

PYSEC-2026-2489 Giskard has a Regular Expression Denial of Service (ReDoS) in RegexMatching Check

Summary The RegexMatching check in the giskard-checks package passes a user-supplied regular expression pattern directly to Python's re.search without any timeout, complexity guard, or pattern validation. An attacker who can control the regex pattern or the text being matched can craft inputs tha...

PYSEC-2026-2643 MetaGPT has an eval injection via a cross-site request forgery attack

A vulnerability was determined in FoundationAgents MetaGPT up to 0.8.2. The impacted element is the function evaluateCode of the file metagpt/environment/minecraft/mineflayer/index.js of the component Mineflayer HTTP API. Executing a manipulation can lead to cross-site request forgery. The attack...

PYSEC-2026-2906 PraisonAI Vulnerable to Server-Side Request Forgery via Unvalidated webhook_url in Jobs API

Summary The /api/v1/runs endpoint accepts an arbitrary webhookurl in the request body with no URL validation. When a submitted job completes success or failure, the server makes an HTTP POST request to this URL using httpx.AsyncClient. An unauthenticated attacker can use this to make the server...

PYSEC-2026-2949 PraisonAIAgents: Arbitrary File Read via read_skill_file Missing Workspace Boundary and Approval Gate

Summary readskillfile in skilltools.py allows reading arbitrary files from the filesystem by accepting an unrestricted skillpath parameter. Unlike filetools.readfile which enforces workspace boundary confinement, and unlike runskillscript which requires critical-level approval, readskillfile has...
