Prior to version 0.3.2, `internal/configgen/generator.go:86,108,119` interpolates the operator-supplied `ListenHost` and `TunDevice` fields raw into a `text/template` that produces the agent's `config.yml`. `internal/web/advanced.go:20-35` accepts both with only `strings.TrimSpace` — no character or shape validation. Version 0.3.2 fixes the issue.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-94"],"references":["https://github.com/forgekeep/nebula-mesh/commit/c1506f7344ab375a145a7449b193af3f19bb41ef","https://github.com/forgekeep/nebula-mesh/issues/126","https://github.com/forgekeep/nebula-mesh/security/advisories/GHSA-7hp6-g3pq-3pc3"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2026-47722","score":0.00467,"percentile":0.40196,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-7hp6-g3pq-3pc3","url":"https://osv.dev/vulnerability/GHSA-7hp6-g3pq-3pc3","summary":"nebula-mesh: Host advanced overrides allow YAML injection into agent config.yml","modified":"2026-06-25T19:56:05.153738157Z","packages":[{"ecosystem":"Go","name":"github.com/juev/nebula-mesh","purl":"pkg:golang/github.com/juev/nebula-mesh","ranges":["<0.3.2"],"fixed":["0.3.2"]}]},{"id":"GO-2026-5223","url":"https://osv.dev/vulnerability/GO-2026-5223","summary":"nebula-mesh: Host advanced overrides allow YAML injection into agent config.yml in github.com/juev/nebula-mesh","modified":"2026-06-25T19:45:15.329619487Z","packages":[{"ecosystem":"Go","name":"github.com/juev/nebula-mesh","purl":"pkg:golang/github.com/juev/nebula-mesh","ranges":["<0.3.2"],"fixed":["0.3.2"]}]}],"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).
