{"cve":"CVE-2026-25534","nvd":{"published":"2026-03-17T18:16:15.063","modified":"2026-06-17T10:24:48.563","status":"Deferred","description":"### Impact\nSpinnaker updated URL Validation logic on user input to provide sanitation on user inputted URLs for clouddriver.  However, they missed that Java URL objects do not correctly handle underscores on parsing.  This led to a bypass of the previous CVE (CVE-2025-61916) through the use of carefully crafted URLs.  Note, Spinnaker found this not just in that CVE, but in the existing URL validations in Orca fromUrl expression handling.  This CVE impacts BOTH artifacts as a result.   \n\n### Patches\nThis has been merged and will be available in versions 2025.4.1, 2025.3.1, 2025.2.4 and 2026.0.0.  \n\n### Workarounds\nYou can disable the various artifacts on this system to work around these limits.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:L","score":9.1},"cwes":["CWE-918"],"references":["https://github.com/spinnaker/spinnaker/commit/7c4737906239a958a468e843239c6785b03d0eda","https://github.com/spinnaker/spinnaker/security/advisories/GHSA-8r8j-gfhg-fw38","https://github.com/spinnaker/spinnaker/security/advisories/GHSA-vrjc-q2fh-6x9h"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-25534","score":0.00256,"percentile":0.17267,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8r8j-gfhg-fw38","url":"https://osv.dev/vulnerability/GHSA-8r8j-gfhg-fw38","summary":"Spinnaker clouddriver and orca URL validation bypass via underscores in hostnames","modified":"2026-09-01T16:15:04.844738053Z","packages":[{"ecosystem":"Maven","name":"io.spinnaker.clouddriver:clouddriver-artifacts","purl":"pkg:maven/io.spinnaker.clouddriver/clouddriver-artifacts","ranges":[">=2025.1.6 <2025.2.4"],"fixed":["2025.2.4"]},{"ecosystem":"Maven","name":"io.spinnaker.clouddriver:clouddriver-artifacts","purl":"pkg:maven/io.spinnaker.clouddriver/clouddriver-artifacts","ranges":[">=2025.3.0 <2025.3.1"],"fixed":["2025.3.1"]},{"ecosystem":"Maven","name":"io.spinnaker.clouddriver:clouddriver-artifacts","purl":"pkg:maven/io.spinnaker.clouddriver/clouddriver-artifacts","ranges":[">=2025.4.0 <2025.4.1"],"fixed":["2025.4.1"]},{"ecosystem":"Maven","name":"io.spinnaker.orca:orca-core","purl":"pkg:maven/io.spinnaker.orca/orca-core","ranges":[">=2025.1.6 <2025.2.4"],"fixed":["2025.2.4"]},{"ecosystem":"Maven","name":"io.spinnaker.orca:orca-core","purl":"pkg:maven/io.spinnaker.orca/orca-core","ranges":[">=2025.3.0 <2025.3.1"],"fixed":["2025.3.1"]},{"ecosystem":"Maven","name":"io.spinnaker.orca:orca-core","purl":"pkg:maven/io.spinnaker.orca/orca-core","ranges":[">=2025.4.0 <2025.4.1"],"fixed":["2025.4.1"]}]}],"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).
