{"cve":"CVE-2026-45723","nvd":{"published":"2026-09-17T20:16:49.347","modified":"2026-09-23T18:12:04.247","status":"Awaiting Analysis","description":"Omni manages Kubernetes on bare metal, virtual machines, or in a cloud. Prior to 1.6.6 and 1.7.3, managementServer.CreateSchematic in internal/backend/grpc/schematics.go passes the caller-controlled TalosVersion field to imageFactoryClient.OverlaysVersions without validating it as a version. An authenticated Operator can submit traversal segments in TalosVersion, and url.URL.JoinPath normalizes them into unintended paths on the configured image-factory host. Omni then issues HTTP GET requests to those paths and reflects error-body content, enabling same-host endpoint probing and possible disclosure of internal diagnostics while preventing redirection to another host or write requests. This issue is fixed in versions 1.6.6 and 1.7.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N","score":2.7},"cwes":["CWE-20","CWE-22","CWE-209","CWE-441","CWE-918"],"references":["https://github.com/siderolabs/omni/commit/13c3f289789842e1fd954d98babb34b94eea1192","https://github.com/siderolabs/omni/commit/3e69e80802624bf322f16aa499d5eafca16d0025","https://github.com/siderolabs/omni/commit/9426c2cabccaa1d442bc8ebf28c16cae2d7c6ff7","https://github.com/siderolabs/omni/pull/2817","https://github.com/siderolabs/omni/releases/tag/v1.6.6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-45723","score":0.00494,"percentile":0.42426,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-c66c-vq6w-fvh5","url":"https://osv.dev/vulnerability/GHSA-c66c-vq6w-fvh5","summary":"Omni: Operator can traverse image-factory API paths via unsanitized `talos_version` in CreateSchematic","modified":"2026-06-25T19:56:02.901826116Z","packages":[{"ecosystem":"Go","name":"github.com/siderolabs/omni","purl":"pkg:golang/github.com/siderolabs/omni","ranges":["<1.6.6"],"fixed":["1.6.6"]},{"ecosystem":"Go","name":"github.com/siderolabs/omni","purl":"pkg:golang/github.com/siderolabs/omni","ranges":[">=1.7.0 <1.7.3"],"fixed":["1.7.3"]}]},{"id":"GO-2026-5316","url":"https://osv.dev/vulnerability/GO-2026-5316","summary":"Omni: Operator can traverse image-factory API paths via unsanitized `talos_version` in CreateSchematic in github.com/siderolabs/omni","modified":"2026-06-25T19:45:30.508253378Z","packages":[{"ecosystem":"Go","name":"github.com/siderolabs/omni","purl":"pkg:golang/github.com/siderolabs/omni","ranges":["<1.6.6",">=1.7.0 <1.7.3"],"fixed":["1.6.6","1.7.3"]}]}],"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).
