CVE-2024-11043
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA Denial of Service (DoS) vulnerability was discovered in the /api/v1/boards/{board_id} endpoint of invoke-ai/invokeai version v5.0.2. This vulnerability occurs when an excessively large payload is sent in the board_name field during a PATCH request. By sending a large payload, the UI becomes unresponsive, rendering it impossible for users to interact with or manage the affected board. Additionally, the option to delete the board becomes inaccessible, amplifying the severity of the issue.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA Denial of Service vulnerability exists in the PATCH /api/v1/boards/{board_id} endpoint of InvokeAI v5.0.2. When an excessively large payload is sent in the board_name field, the server consumes excessive resources causing the UI to become unresponsive, rendering the board unmanageable and the delete function inaccessible.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify InvokeAI versionRun 'invokeai --version' or check the package version via pip (pip show invokeai) to confirm the installed versionAffected if Version is 5.0.2 or falls within an affected range that includes this vulnerability
-
Confirm API server is runningCheck if the InvokeAI API server is active and listening on its expected port (default 9090), using commands like 'curl http://localhost:9090/health' or checking running processesAffected if API server is running and accessible on the network
-
Verify boards endpoint accessibilitySend a test request to PATCH /api/v1/boards/{board_id} to confirm the endpoint exists and accepts requests. Use a valid board_id from your environment.Affected if Endpoint responds and accepts requests (even with invalid payload)
-
Check API request size configurationInspect InvokeAI API configuration files or startup parameters for any request size limits, payload restrictions, or rate limiting configured on the board_name field or general endpointAffected if No request size limits or payload restrictions are configured for the boards API endpoint
The environment is affected if running InvokeAI v5.0.2 with the API accessible and no request size limits configured on the boards endpoint.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement input validation with length restrictions on the board_name field and add request size limits at the API level to prevent large payload DoS attacks.
