{"cve":"CVE-2026-48025","nvd":{"published":"2026-07-28T18:17:20.583","modified":"2026-10-23T23:10:00.157","status":"Deferred","description":"nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network. Prior to version 0.3.7, internal/pki/resolver.go:36-64 constructs a CAManager with the plaintext ed25519.PrivateKey after unwrapping via the master key; internal/pki/ca.go:13-16 stores it. Callers at internal/api/enroll.go:116, internal/api/updates.go:297, and internal/api/mobile_bundle.go:40 use the manager for one Sign() and drop the reference on function return — but the underlying slice contents are not wiped before release. The keystore package's contract (internal/keystore/keystore.go doc: \"Callers MUST zeroise the returned plaintext DEK as soon as it is no longer needed\") is not met by the CAManager consumer. Decrypted CA private keys persist in process heap until Go's GC scavenges the underlying slice — minutes to hours under load, indefinitely on idle servers. This issue has been patched in version 0.3.7.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":null,"cwes":["CWE-244"],"references":["https://github.com/forgekeep/nebula-mesh/commit/bca1d5914fbaf3517d3b86145a802c00de4a8122","https://github.com/forgekeep/nebula-mesh/releases/tag/v0.3.7","https://github.com/forgekeep/nebula-mesh/security/advisories/GHSA-8h84-fhqq-q58v"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2026-48025","score":0.00507,"percentile":0.42959,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-8h84-fhqq-q58v","url":"https://osv.dev/vulnerability/GHSA-8h84-fhqq-q58v","summary":"nebula-mesh: Decrypted CA private key persists in heap after signing","modified":"2026-06-26T21:00:09.480246138Z","packages":[{"ecosystem":"Go","name":"github.com/juev/nebula-mesh","purl":"pkg:golang/github.com/juev/nebula-mesh","ranges":["<0.3.7"],"fixed":["0.3.7"]},{"ecosystem":"Go","name":"github.com/forgekeep/nebula-mesh","purl":"pkg:golang/github.com/forgekeep/nebula-mesh","ranges":["<0.3.7"],"fixed":["0.3.7"]}]},{"id":"GO-2026-5255","url":"https://osv.dev/vulnerability/GO-2026-5255","summary":"nebula-mesh: Decrypted CA private key persists in heap after signing in github.com/forgekeep/nebula-mesh","modified":"2026-06-25T19:45:22.853334296Z","packages":[{"ecosystem":"Go","name":"github.com/forgekeep/nebula-mesh","purl":"pkg:golang/github.com/forgekeep/nebula-mesh","ranges":["<0.3.7"],"fixed":["0.3.7"]}]}],"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).
