An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-59836 exists.\n\nAffected packages and fixed versions:\n- github.com/siderolabs/omni (Go): affected all versions; fixed in 1.0.2, 1.1.5\n- github.com/siderolabs/omni (Go): affected all versions; fixed in 1.0.2\n- github.com/siderolabs/omni (Go): affected all versions; fixed in 1.0.2\n- github.com/siderolabs/omni (Go): affected from 1.1.0-beta.0; fixed in 1.1.5\n- github.com/siderolabs/omni (Go): affected from 1.1.0-beta.0; fixed in 1.1.5\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-59836/ (Markdown: https://insights.sbomify.com/CVE-2025-59836/index.md)","id":"CVE-2025-59836","markdown":"https://insights.sbomify.com/CVE-2025-59836/index.md","name":"CVE-2025-59836","record":{"aliases":["GHSA-4p3p-cr38-v5xp","GO-2025-4021"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Kubernetes management server","requires_auth":"none","summary":"Unauthenticated attackers can cause a server panic and denial of service by sending empty resource requests to the Omni API.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"omni","vendor":"siderolabs"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-703","name":"Improper Check or Handling of Exceptional Conditions"},{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Omni manages Kubernetes on bare metal, virtual machines, or in a cloud. 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.
