Hatchet is a platform for orchestrating background tasks, AI agents, and durable workflows at scale. Prior to 0.91.1, api-contracts/openapi/paths/v1/workflow-runs/workflow_run.yaml defines the GET /api/v1/stable/durable-tasks/{durable-task} endpoint implemented by listDurableEventLog without requiring the target tenant as a parent resource, allowing an authenticated user who obtains another tenant's durable task UUID to read that task's event log. Disclosed data can include task display names, workflow identifiers, user messages, wait conditions, branching logic, and timing information. This issue is fixed in version 0.91.1.

CVE-2026-911644.3 MED—
——0Warpgate is an open source SSH, HTTPS and MySQL bastion host for Linux. From 0.23.0 until 0.27.3, HTTP API token authentication resolves ConfigProvider::validate_api_token into RequestAuthorization::UserToken without enforcing the owning user's allowed_ip_ranges against the trusted client address in warpgate-protocol-http/src/common.rs. An attacker holding a leaked, phished, or exfiltrated X-Warpgate-Token can therefore use it from a prohibited network location. Deployments without allowed_ip_ranges are unaffected, and HTTP target proxying plus SSH, MySQL, PostgreSQL, RDP, VNC, and Kubernetes paths do not accept this vulnerable HTTP token flow. This issue is fixed in version 0.27.3.1hCVE-2026-617446.5 MED—
——0InvenTree is an Open Source Inventory Management System. Prior to 1.4.0, POST /api/barcode/ accepts an attacker-synthesized internal JSON barcode containing a lowercase model label and integer primary key, while BarcodeView uses IsAuthenticatedOrReadScope and requires only authentication or a general read scope. The built-in barcode plugin selects the object with model.objects.get(pk=...), and InvenTreeBarcodeMixin.format_matched_response() returns the complete model serializer output as instance without checking the caller's per-model view role. A low-privilege user can enumerate primary keys for parts, stock, locations, supplier and manufacturer parts, orders, and builds to disclose commercially sensitive inventory, pricing, supplier, customer, and order data. This issue is fixed in version 1.4.0.1hCVE-2026-775608.1 HIG—
——0Tinyauth is an authentication and authorization server. Prior to 5.1.2, Tinyauth compares forwarded hostnames case-sensitively while reverse proxies route equivalent hostnames case-insensitively, allowing an authenticated low-privilege user to bypass per-app access controls with a differently cased hostname. The lookup in internal/service/access_controls_service.go through lookupStaticACLs and GetAccessControls, and the Docker-label fallback in internal/service/docker_service.go through GetLabels, can miss the configured app and return an empty access-control object. internal/controller/proxy_controller.go proxyHandler then treats the empty user, group, OAuth, LDAP, and IP restrictions as permissive and returns an authenticated result for an app that should exclude the user. Unauthenticated users remain subject to login, and global login-time allowlists are not bypassed. This issue is fixed in version 5.1.2.3hCVE-2026-889784.3 MED—
——0Hatchet is a platform for orchestrating background tasks, AI agents, and durable workflows at scale. Prior to 0.106.1, the WorkerStatus gRPC polling path in pkg/repository/durable_events.go passes caller-supplied durable task, node, and branch identifiers to ListSatisfiedEntries without a tenant filter, allowing an authenticated tenant worker that knows another tenant's durable-task UUID to retrieve matching durable event-log records. The UUIDv4 requirement makes exploitation unlikely, and single-tenant deployments are unaffected in practice. This issue is fixed in version 0.106.1.4hCVE-2026-55563——
——0Feast is the open source feature store for AI and machine learning. Prior to 0.65.0, .github/workflows/pr_integration_tests.yml uses pull_request_target with the synchronize event and preserves ok-to-test, approved, or lgtm labels across newly pushed commits, allowing a fork contributor to obtain approval for a benign revision and then run changed code from refs/pull/${{ github.event.pull_request.number }}/merge through privileged make targets. The job exposes GCP, AWS, and Snowflake credentials to that code, enabling runner code execution, credential disclosure, and possible access to downstream cloud resources. An external label-removal integration could mitigate the condition, but no repository workflow provided that protection. This issue is fixed in version 0.65.0.2hCVE-2026-801108.1 HIG—
——0A flaw was found in pki-core. The v2 REST ACL filter selects a tie-breaking permission for colliding literal and wildcard ACL keys using lexicographic string comparison rather than specificity, causing a wildcard-mapped permission to override a more specific literal-mapped permission when both match. In the CA's profile-management REST API this allows a request to POST /v2/profiles/raw -- intended to require Administrator-level profiles.create permission -- to instead be authorized under the lower-privileged profiles.approve permission held by the default Certificate Manager Agents group. The highest threat from this vulnerability is to confidentiality and integrity of the certificate authority's issuance policy.5h
