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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":null,"cwes":["CWE-352"],"references":["https://github.com/forgekeep/nebula-mesh/releases/tag/v0.3.3","https://github.com/forgekeep/nebula-mesh/security/advisories/GHSA-273q-qgh5-wrj6","https://github.com/forgekeep/nebula-mesh/security/advisories/GHSA-273q-qgh5-wrj6"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2026-47725","score":0.00187,"percentile":0.08258,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-273q-qgh5-wrj6","url":"https://osv.dev/vulnerability/GHSA-273q-qgh5-wrj6","summary":"nebula-mesh's web UI lacks CSRF tokens on /ui/* mutating endpoints","modified":"2026-06-17T00:26:22.896640400Z","packages":[{"ecosystem":"Go","name":"github.com/juev/nebula-mesh","purl":"pkg:golang/github.com/juev/nebula-mesh","ranges":["<0.3.3"],"fixed":["0.3.3"]}]},{"id":"GO-2026-5049","url":"https://osv.dev/vulnerability/GO-2026-5049","summary":"nebula-mesh's web UI lacks CSRF tokens on /ui/* mutating endpoints in github.com/juev/nebula-mesh","modified":"2026-06-17T00:15:12.887013832Z","packages":[{"ecosystem":"Go","name":"github.com/juev/nebula-mesh","purl":"pkg:golang/github.com/juev/nebula-mesh","ranges":["<0.3.3"],"fixed":["0.3.3"]}]}],"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).
