Prior to version 0.3.3, every /ui/* POST / PUT / PATCH / DELETE route processes the request as soon as the session cookie validates. SameSite=Lax on the session cookie prevents most cross-site form submits but does not protect: top-level form-submit navigations from third-party pages (some browsers still send Lax cookies on top-level POSTs); same-registrable-domain attackers (sibling-subdomain XSS, subdomain takeover); the GET /ui/logout route, which a third-party <img src=\".../ui/logout\"> can force-trigger. This issue has been patched in version 0.3.3.","published":"2026-07-28T17:56:29.651Z","modified":"2026-08-12T03:51:31.010821122Z","cvss":null,"epss":{"score":0.00154,"percentile":0.0485,"asOf":"2026-09-02"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/juev/nebula-mesh","fixedVersion":"0.3.3"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/forgekeep/nebula-mesh/releases/tag/v0.3.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/47xxx/CVE-2026-47725.json"},{"type":"ADVISORY","url":"https://github.com/forgekeep/nebula-mesh/security/advisories/GHSA-273q-qgh5-wrj6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47725"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:31.010821122Z"}}
