Incident date: February 12, 2026 | Published: February 25, 2026 | Source: GitHub Security Advisory | Classification confidence: 53%

This incident is part of the public archive and includes explicit AI-related signals from the cited source material. Review methodology.

Arbitrary WASM Code Execution via AnnotationOverrideFlight Injection in Yoke ATC This vulnerability exists in the Air Traffic Controller (ATC) component of Yoke, a Kubernetes deployment tool. It allows users with CR create/update permissions to execute arbitrary WASM code in the ATC controller context by injecting a malicious URL through the overrides.yoke.cd/flight annotation. The ATC controller downloads and executes the WASM module without proper URL validation, enabling attackers to create arbitrary Kubernetes resources or potentially escalate privileges to cluster-admin level.

Why This Is AI-Related

This page is treated as AI-specific because the source material references copilot, which places the issue inside an AI workflow, model, assistant, or supporting dependency rather than a generic software bulletin.

  • copilot

Affected Workflow

Review the AI product, dependency, and integration points mentioned in the source advisory before broadening remediation.

Likely Attack Path

The advisory indicates a security path that can affect AI applications, assistants, models, or connected automation workflows if the component is deployed.

Impact

The issue can create a path to command execution inside an AI-facing product, plugin, copilot, or supporting service runtime. Severity HIGH. Classification confidence 53%. Source channel GHSA.

Detection And Triage Signals

  • New security events tied to the affected component or advisory identifier
  • Changes in AI workflow behavior, access logs, or plugin execution after the advisory window
  • Evidence that the vulnerable version is active in environments that process sensitive data

Recommended Response

  • Identify every environment that runs the affected AI plugin, assistant, CLI, or supporting package.
  • Patch or isolate the vulnerable component and remove risky execution permissions while validation is in progress.
  • Review process execution, outbound connections, and file-write logs for signs of post-exploitation activity.

Compliance And Business Impact

Even when exploit details are still emerging, delayed triage can widen operational and compliance exposure around AI systems.
