Descripción resumida

MikroTik RouterOS contains a missing authentication for critical function vulnerability which allows kernel memory disclosure and denial of service in the btest service.

Acción requerida

Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes). Follow applicable BOD 26-04 guidance for cloud services or discontinue use of the product if mitigations are unavailable. Stakeholders are responsible for evaluating each asset's internet exposure and ensuring adherence to BOD 26-04 patching guidelines.

Descripción técnica

RouterOS accepts a "related" btest connection before the corresponding primary session has completed authentication. An unauthenticated client can use this state to start an IPv4 UDP test. With "random-data=false", the sender transmits an uninitialized tail from a kernel packet buffer. A separate unchecked, inverted packet-size interval causes unsigned integer underflow, anomalously large fragmented output, and can restart the RouterOS kernel. This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable)

—

——0HKUDS Vibe-Trading from 0.1.0 before 0.1.7 contains a missing authentication vulnerability that allows unauthenticated attackers to access the FastAPI surface because require_auth() returns early when API_AUTH_KEY is unset. Attackers can post messages to /sessions/{id}/messages to trigger root shell commands via BashTool, upload .py or .sh files via /upload, read session histories, and obtain partial API keys.18h CVE-2026-1140926.5 MED

—

——0Trigger.dev before 4.5.0 performs no authentication or organization check in the action handler of the dashboard run replay route (resources.taskruns.$runParam.replay) and looks up the run by friendlyId alone. A remote attacker who knows a victim's run friendlyId can replay it into an environment of their choosing, exposing the victim's task payload or running the task again with the victim's secrets.18h CVE-2026-1140907.1 ALT

—

——0Trigger.dev cli-v3 from 3.0.0 before 4.5.4 contains a missing authentication vulnerability in the trigger dev --mcp server, which binds all network interfaces and exposes the /sse and /messages endpoints. LAN attackers or malicious web pages can send MCP tools/call requests to invoke trigger-task, cancel-run, list-runs, and get-run-logs using the developer's stored access token.18h CVE-2026-1140865.3 MED

—

——0Trigger.dev before 4.5.5 contains a missing authentication vulnerability in the realtime streams POST handler that allows unauthenticated attackers to inject data into run streams. Attackers can send POST requests to /realtime/v1/streams/:runId/:streamId with a predictable run friendlyId to inject arbitrary data into any environment's realtime stream, including production.18h CVE-2026-1140857.9 ALT

—

——0Trigger.dev through 4.7.6 contains a missing authentication vulnerability in the supervisor workload server that allows workloads to manipulate runs belonging to other deployments without ownership verification. Attackers with network access and a valid run/snapshot pair can call the attempts/start endpoint to obtain resolved environment variables and run JWTs, or start, complete, and suspend other tenants' runs.18h CVE-2026-1136483.1 BAJ

——0ApostropheCMS is an open-source Node.js content management system. Prior to 3.7.1 of the import-export module, the API endpoint POST /api/v1/@apostrophecms/import-export/clean-export in @apostrophecms/import-export lacks authentication and authorization checks. Any client—including unauthenticated anonymous users who have obtained the standard CSRF cookie from visiting the site—can directly invoke this route and trigger the underlying self.cleanExport(req) method. This issue is fixed in version 3.7.1.23h
