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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-476","CWE-703"],"references":["https://github.com/siderolabs/omni/commit/1396083f766a1b0380e9949968d7fc17b7afecaa","https://github.com/siderolabs/omni/commit/1fd954af64985a8b3dbf5b11deddbf7cd953f5ae","https://github.com/siderolabs/omni/security/advisories/GHSA-4p3p-cr38-v5xp"],"products":["siderolabs:omni"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2025-59836","score":0.00582,"percentile":0.475,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4p3p-cr38-v5xp","url":"https://osv.dev/vulnerability/GHSA-4p3p-cr38-v5xp","summary":"Omni is Vulnerable to DoS via Empty Create/Update Resource Requests","modified":"2025-11-05T22:07:29Z","packages":[{"ecosystem":"Go","name":"github.com/siderolabs/omni","purl":"pkg:golang/github.com/siderolabs/omni","ranges":[">=1.1.0-beta.0 <1.1.5"],"fixed":["1.1.5"]},{"ecosystem":"Go","name":"github.com/siderolabs/omni","purl":"pkg:golang/github.com/siderolabs/omni","ranges":["<1.0.2"],"fixed":["1.0.2"]}]},{"id":"GO-2025-4021","url":"https://osv.dev/vulnerability/GO-2025-4021","summary":"Omni is Vulnerable to DoS via Empty Create/Update Resource Requests in github.com/siderolabs/omni","modified":"2026-03-03T04:56:59.939893Z","packages":[{"ecosystem":"Go","name":"github.com/siderolabs/omni","purl":"pkg:golang/github.com/siderolabs/omni","ranges":["<1.0.2",">=1.1.0-beta.0 <1.1.5"],"fixed":["1.0.2","1.1.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
