changedetection.io's REST API resources are protected by an @auth.check_token decorator validating the caller's x-api-key header, except the Spec resource registered at /api/v1/full-spec (changedetectionio/api/Spec.py), whose get method carries neither @auth.check_token nor @validate_openapi_request.

CVE-2026-585749.8 CRI—
——0Dell PowerStore contains a Missing Authentication for Critical Function vulnerability. An unauthenticated attacker with network access to the restricted management interface could potentially exploit this vulnerability to read internal system information from the appliance filesystem. This is a Critical vulnerability as it could expose sensitive information and credentials which allow full administrative access to the array.5hCVE-2026-826418.6 HIG—
——0keploy versions 3.1.0 through 3.6.25 bind the agent control-plane HTTP server to all interfaces without authentication, exposing endpoints that stream TLS session keys and traffic data. Attackers can access the /agent/pcap/keylog endpoint to retrieve NSS keylog lines and decrypt recorded TLS traffic, or invoke /agent/stop and /agent/storemocks to manipulate recording sessions.22hCVE-2026-824738.2 HIG28.3%
——8KubeEdge CloudCore through 1.23.1 accepts node task status reports on its HTTPS server without authentication verification. Attackers can reach CloudCore on port 10002 to mark upgrade jobs as succeeded or failed, deceiving the control plane about node upgrade status and blocking further upgrade scheduling.2dCVE-2026-824727.5 HIG33.7%
——10Documenso before 2.13.0 accepts PDF file uploads on the /api/files/upload-pdf endpoint without requiring authentication, session tokens, or API credentials. Unauthenticated attackers can upload arbitrary PDF files indefinitely to exhaust storage resources or fill the database with unlinked document records.2dCVE-2026-824529.8 CRI38.0%
——11rust-iot-platform through commit 5df942ab contains an authentication bypass vulnerability where most REST API routes lack authentication guards in their handler signatures. Unauthenticated attackers can create, update, list, retrieve, and delete user accounts by directly accessing unprotected endpoints without providing valid credentials.2dCVE-2026-55678—31.7%
——10Arc is an open, SQL-native time-series database for telemetry. From 26.02.1 until 26.06.2, Arc Enterprise clustering accepts cluster join requests without authentication when cluster.enabled is true but cluster.shared_secret is not configured. The defaults in internal/config/config.go set cluster.enabled to false, cluster.cluster_name to arc-cluster, cluster.coordinator_addr to :9100, cluster.shared_secret to an empty value, and cluster.tls_enabled to false, while cmd/arc/main.go requires cluster.shared_secret only when cluster.replication_enabled is true. JoinRequest in internal/cluster/protocol/messages.go accepts attacker-controlled node_id, role, raft_addr, api_addr, and coord_addr values, plus optional auth_nonce, auth_timestamp, and auth_hmac fields. The join path in internal/cluster/coordinator.go validates HMAC authentication only when the configured shared secret is non-empty and otherwise proceeds after only the cluster-name check. An accepted node is marked healthy, added as a Raft voter or registered locally, and becomes available through internal/cluster/registry.go to the routing logic in internal/cluster/router.go. The forwardRequest path in internal/cluster/router.go builds its target from node.APIAddress and copies Authorization and x-api-key headers with the request, so a rogue node selected for a forwarded query or write can receive authentication headers, request bodies, database and measurement names, and operational metadata. Heartbeat in internal/cluster/protocol/messages.go also lacks HMAC fields, and internal/cluster/coordinator.go updates node state from supplied node_id and state values without authentication. An unauthenticated network attacker who can reach the coordinator port and knows the cluster name can therefore become a trusted cluster node, mutate cluster membership, be submitted as a Raft voter, intercept topology-dependent forwarded requests, divert or forge operations, and blackhole or delay traffic. The default standalone configuration is not reachable because cluster.enabled is false, but Enterprise cluster deployments with clustering enabled and no shared secret are affected. This issue is fixed in version 26.06.2.3d
