The 303 Location header carries the raw token in the query string. Open browser DevTools → Network → response headers; or check the reverse-proxy access log; or check the operator-detail page's `Referer`-emitting fetches.\n\n## Suggested fix\nStash the raw key in a one-shot server-side flash storage (e.g., a row in `operator_sessions` keyed by session token, with a `one_shot_token` column and `consumed_at`) or in a short-lived signed cookie. Render the key once inline on the detail page after the redirect, and clear the storage on render. Pattern mirrors the recovery-codes display in the TOTP flow.\n\nIf the flash-storage refactor is too invasive, the minimal fix is to render the key inline via a `POST` → `200 OK with HTML` (no redirect), losing the post-redirect-get idiom but eliminating the URL exposure.\n\nAlso fix `name` query encoding with `url.QueryEscape` regardless of which fix shape lands.\n\n## CVSS estimate\nAV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N — 5.5 (medium). AV:L because realistic exploit requires log-read access on shared infrastructure (proxy, CDN, browser-history backup) the operator's session touches.","state":0,"publishedAt":"2026-06-10T22:13:45+00:00","modifiedAt":"2026-06-25T19:56:25.3265068+00:00","affected":[{"ecosystem":"Go","name":"github.com/juev/nebula-mesh","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.3.2"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/juev/nebula-mesh/security/advisories/GHSA-9pg3-25fq-p6cc","https://github.com/juev/nebula-mesh"],"sourceUrl":"https://github.com/advisories/GHSA-9pg3-25fq-p6cc","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-9pg3-25fq-p6cc","identifiers":["GHSA-9pg3-25fq-p6cc","CVE-2026-47768","GO-2026-5294"]},"retained":false,"historicalAffected":[]},{"revision":"2c0f475cd5624f5b9c4501c30a121e56","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-5294","aliases":["CVE-2026-47768","GHSA-9pg3-25fq-p6cc"],"title":"nebula-mesh: Newly-minted operator API key exposed in redirect URL (Referer, history, proxy logs) in github.com/juev/nebula-mesh","description":"nebula-mesh: Newly-minted operator API key exposed in redirect URL (Referer, history, proxy logs) in github.com/juev/nebula-mesh","state":0,"publishedAt":"2026-06-25T18:43:19+00:00","modifiedAt":"2026-06-25T19:45:26.3926089+00:00","affected":[{"ecosystem":"Go","name":"github.com/juev/nebula-mesh","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.3.2"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/juev/nebula-mesh/security/advisories/GHSA-9pg3-25fq-p6cc"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-5294","license":"OSV · upstream source license applies","key":"osv:GO-2026-5294","identifiers":["GO-2026-5294","CVE-2026-47768","GHSA-9pg3-25fq-p6cc"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
