{"id":"CVE-2026-58080","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-58080","summary":null,"details":"In Eclipse Milo versions 1.0.0 through 1.1.4, `OpcUaServerConfig.copy()` fails to preserve a configured `RoleMapper`. On servers that rely on role permissions and construct the running configuration through `copy()`, sessions receive no role IDs and the default access controller skips role-permission checks, allowing an anonymous client where anonymous sessions are permitted to read role-permission metadata, invoke protected methods, or delete protected nodes.","published":"2026-08-04T12:05:10.547Z","modified":"2026-08-12T16:09:50.021994Z","cvss":null,"epss":{"score":0.00269,"percentile":0.19141,"asOf":"2026-08-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":{"url":"https://github.com/eclipse-milo/milo/commit/d51f03e9a75f313ab41c3d68d809f4b922073f1a","label":"eclipse-milo/milo@d51f03e"},"references":[{"type":"WEB","url":"https://gitlab.eclipse.org/security/cve-assignment/-/work_items/180"},{"type":"WEB","url":"https://gitlab.eclipse.org/security/vulnerability-reports/-/work_items/598"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/58xxx/CVE-2026-58080.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58080"},{"type":"FIX","url":"https://github.com/eclipse-milo/milo/commit/d51f03e9a75f313ab41c3d68d809f4b922073f1a"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T16:09:50.021994Z"}}
