CVE-2025-29922 Â (opens in a new tab)How to fix?
Upgrade github.com/kcp-dev/kcp/pkg/virtual/apiexport/authorizer to version 0.26.3 or higher.
Overview
Affected versions of this package are vulnerable to Improper Authorization through the APIExport VirtualWorkspace. An attacker can create and delete objects in arbitrary target workspaces without the necessary permissions by exploiting this vulnerability.
Workaround
This vulnerability can be mitigated by minimizing the set of people with apiexport/content sub-resource access to APIExport resources across all workspaces and filtering incoming requests in a reverse proxy with logic similar to the authorizer added in the referenced pull request.
