Prior to 2026.1.0, 2026.0.3, 2025.4.4, and 2025.3.3, unsafe YAML processing bypasses safe deserialization when using CloudFormation deployments or CloudFoundry baking. The use of a non-safe constructor allows arbitrary loading of Java classes, leading to remote code execution. This issue is fixed in versions 2026.1.0, 2026.0.3, 2025.4.4, and 2025.3.3.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-470","CWE-502"],"references":["https://github.com/spinnaker/spinnaker/commit/4cbe1d5fea9df573aadfd8b093fb4b594b354ee5","https://github.com/spinnaker/spinnaker/commit/e57c0db4584b398473a7bbb19402ce6c1e89b627","https://github.com/spinnaker/spinnaker/commit/f69d7b534d068ed74d0d3a1fbf17e2c945d36e5e","https://github.com/spinnaker/spinnaker/security/advisories/GHSA-c8q4-9h32-2ww8"],"products":["linuxfoundation:spinnaker"],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-44795","score":0.01012,"percentile":0.63207,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-c8q4-9h32-2ww8","url":"https://osv.dev/vulnerability/GHSA-c8q4-9h32-2ww8","summary":"Spinnaker has non-safe yaml deserialization, allowing RCE when using specific types","modified":"2026-09-10T03:51:08.726265701Z","packages":[{"ecosystem":"Maven","name":"io.spinnaker.rosco:rosco-core","purl":"pkg:maven/io.spinnaker.rosco/rosco-core","ranges":["<2025.3.3"],"fixed":["2025.3.3"]},{"ecosystem":"Maven","name":"io.spinnaker.orca:orca-core","purl":"pkg:maven/io.spinnaker.orca/orca-core","ranges":["<2025.3.3"],"fixed":["2025.3.3"]},{"ecosystem":"Maven","name":"io.spinnaker.rosco:rosco-core","purl":"pkg:maven/io.spinnaker.rosco/rosco-core","ranges":[">=2025.4.0 <2025.4.4"],"fixed":["2025.4.4"]},{"ecosystem":"Maven","name":"io.spinnaker.rosco:rosco-core","purl":"pkg:maven/io.spinnaker.rosco/rosco-core","ranges":[">=2026.0.0 <2026.0.3"],"fixed":["2026.0.3"]},{"ecosystem":"Maven","name":"io.spinnaker.orca:orca-core","purl":"pkg:maven/io.spinnaker.orca/orca-core","ranges":[">=2025.4.0 <2025.4.4"],"fixed":["2025.4.4"]},{"ecosystem":"Maven","name":"io.spinnaker.orca:orca-core","purl":"pkg:maven/io.spinnaker.orca/orca-core","ranges":[">=2026.0.0 <2026.0.3"],"fixed":["2026.0.3"]}]}],"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).
