Descrição técnica

Malcolm's front nginx reverse proxy defines a "Dashboards → Arkime shortcut" location using a case-insensitive regex matcher but a case-sensitive rewrite. A request whose path segment is not exact-lowercase (for example /IDDASH2ARK/...) enters the location (the matcher fires) but evades the rewrite (no redirect is issued), so nginx falls through to the location's proxy_pass to the Arkime backend. That location is the one proxied location in the shipped config that does not include the per-location authentication file, so the request reaches Arkime unauthenticated. The same location also forwards a client-supplied X-Forwarded-User header un-overwritten, and Arkime is configured to trust X-Forwarded-User as the authenticated username — so an unauthenticated network caller can reach the Arkime backend while supplying a forged, auto-provisioned identity.

CVE-2026-1218374.3 MÉD

—

———A flaw was found in the REST Data Panache component of Quarkus. When a security constraint is applied to an entity property using the @SecureField annotation on its getter method rather than the field itself, the generated REST resource fails to enforce this constraint for filtering and sorting operations. This allows an authenticated user to infer sensitive data values by observing which records match specific filter criteria or how they are ordered, even though the values are omitted from the final response.7h CVE-2026-630179.0 CRÍ

———Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.16.1, the multi-user API server treats the empty namespace used by shared or global pipelines as an authorization exception for modification and deletion operations. An authenticated user can modify or delete shared pipeline definitions and versions without the required Kubernetes RBAC permissions, compromising their integrity and availability. Read-only access to shared pipelines remains intentional, single-user deployments intentionally bypass multi-user checks, and execution of a modified pipeline is a conditional downstream consequence. The separate shared-pipeline multipart upload authorization path is outside this advisory and is not remediated by version 2.16.1. This issue is fixed in version 2.16.1.14h CVE-2026-1029436.5 MÉD

———Dagu is a workflow engine with a built-in Web user interface. Prior to version 2.11.0, its MCP dagu_read operation with target dag_spec invokes the DAG specification API directly, bypassing the HTTP middleware introduced for CVE-2026-33344. The underlying resolver does not restrict resolved paths to configured DAG directories. An authenticated attacker with a viewer-role API key can supply an absolute or traversing path to read .yaml or .yml files outside those directories that are accessible to the Dagu process. The affected operation does not provide write or execution capability. This issue is fixed in version 2.11.0.14h CVE-2026-889835.0 MÉD

———Kubeflow Pipelines enables users to build and deploy portable, scalable machine learning workflows. Prior to 2.17.0, the API server's pipeline and pipeline-version creation paths fetch a caller-supplied pipelineURL without restricting the destination. An authenticated caller with permission to create a pipeline or pipeline version can make requests from the API server to internal services and observe a limited status-code oracle. Arbitrary response-body disclosure, credential theft, and integrity or availability impact are not established. This issue is fixed in version 2.17.0.15h CVE-2026-85076—

———Cronicle is a multi-server task scheduler and runner, with a web based front-end UI. Prior to 0.9.124, an authenticated non-admin with run_events, create_events, or edit_events privilege can supply undeclared keys in event params through api_create_event, api_update_event, or api_run_event. lib/api.js and lib/api/event.js validate the parameter object without restricting its keys, and lib/job.js uppercases those keys and applies them to the child process environment after administrator-defined plugin variables. A key that collides with a security-sensitive environment variable can therefore override the plugin execution context and may cause privilege escalation, arbitrary code execution, data access, or service disruption depending on the plugin and runtime. This issue is fixed in version 0.9.124.16h
