Prior to 1.1.5 and 1.0.2, there is a nil pointer dereference vulnerability in the Omni Resource Service allows unauthenticated users to cause a server panic and denial of service by sending empty create/update resource requests through the API endpoints. The vulnerability exists in the isSensitiveSpec function which calls grpcomni.CreateResource without checking if the resource's metadata field is nil. When a resource is created with an empty Metadata field, the CreateResource function attempts to access resource.Metadata.Version causing a segmentation fault. This vulnerability is fixed in 1.1.5 and 1.0.2."}], "lastModified": "2025-12-04T21:33:52.730", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:siderolabs:omni:*:*:*:*:*:kubernetes:*:*", "vulnerable": true, "matchCriteriaId": "B7B04852-C400-4D56-9C77-EF08063D24DE", "versionEndExcluding": "1.0.2"}, {"criteria": "cpe:2.3:a:siderolabs:omni:*:*:*:*:*:kubernetes:*:*", "vulnerable": true, "matchCriteriaId": "2102EFDA-BE62-4587-A556-98CF28167D6D", "versionEndExcluding": "1.1.5", "versionStartIncluding": "1.1.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
